    This seems like a good time to educate myself about the application (and objection) process.

    The bureaucracy seems precision-engineered to stultify, but apparently the public have 104 days after “String Confirmation Day” (17th Nov; capitalization theirs) to lodge objections, assuming the “GAC” doesn’t beat them to it…

    https://newgtldprogram.icann.org/en/application-rounds/round...

    …of course there’s a “filing fee,” priced in “hours of a panel of lawyers’ time,” to lodge such an objection…

    https://newgtldprogram-2026-agb.icann.org/en/8-module-4-comm...

    …welp, hope somebody more organized (and better-funded) than I can organize an objection. Much as I feel like I’m giving up my right to gripe by assuming somebody else will come along to do the weeding.

    Posting because OpenWRT, possibly others as well, assign .lan names to devices on the LAN by default. People who make use of this might want to follow the application, and, if it goes through, either change the name or make sure queries can't get incorrectly get sent to upstream resolvers.

    Regarding that last point, I've had issues with dnsmasq in the past where it was remotely resolving domains even when they were configured to resolve locally. For .lan domains, this could be disastrous because I often send plaintext traffic to them. I did submit a fix/workaround[0], but it's still something to look out for. If anyone knows more about this issue or other ways queries could leak, please share!

      RFC 8375: Special-Use Domain 'home.arpa.' is supposed to be used for this.

      https://www.rfc-editor.org/info/rfc8375/

      • esskay 23 minutes ago
        and most people dont use it because its an incredibly poor name.
      • Palomides 12 minutes ago
        RFCs were originally formalization of what was being used in practice, home.arpa was chosen apparently for reasons of beauracratic convenience rather than what would best serve existing users, who all would prefer .lan and continue to do so since that was published in 2018
      • pqb 28 minutes ago
        It would be awesome if Ubiquity will actually follow this RFC too. The Amplifi product line from Ubiquity have `.lan` support but no `home.arpa`.

        Internal. is also an valid option. I moved everything there about a year ago
      • c0l0 34 minutes ago
        That's nice and all, but OpenWrt (and its use of .lan) predates this particular RFC by a rough 14 years.

        I hope the gTLD application gets struck down.

        • pwdisswordfishq 25 minutes ago
          God forbid OpenWrt ever receives an update or something.

            If you actually think it's a trivial affair to change a well-established default with more than 20 years of history that is, on top of all other difficulties that such a change typically encompasses, used to identify and name things, I hereby beg you to never design or provide any kind of infrastructure.

        But what if my LAN is in the garage?
    • montecarl 28 minutes ago
      This reminds me of when I used to do IT work for small businesses in college. One printing company I worked for, had about 100 computers on their network, and was using public ipv4 addresses, that they did not own, on their internal network. I forget what range they were using now. But imagine seeing a DHCP server handing out addresses like 142.250.110.1/16 on a LAN and the public ip being something totally different.

      It was funny, because when I brought it up to them, it was hard to articulate why it was a problem and I couldn't convince them it was worth the effort of trying to fix. They never ran into a specific issue due to this while I was there but it felt so gross.

      • masfuerte 14 minutes ago
        The problem is that they wouldn't be able to talk to any internet service that legitimately used those addresses. Whether that was likely to be a problem very much depends on whose addresses they were.

        When I was working with Linux based kiosks and PoS systems I had a good share of issues with the Microsoft MVP signature use of .local on their forests. Back then their training material recommended .local for Active Directory services.

        It's always hard because when you contrive possible examples of how it goes wrong, every single example sounds contrived because of course they are contrived.

        Sure one day your printer might start spewing random json code meant for some microservice of the rightful IP owner.

        Sure the IP's might be owned by the Air Force and one day they might start getting traffic from your pos ipad that they decide looks like an attempt to attack one of their internal secret networks...

        Sure one day traffic meant to go to your printer ends up flooding and dossing a windmill controller, preventing the rightful operators from turning it the right direction during bad weather and causing $25M damage...

      • deno 15 minutes ago
        There's a good reason to do this if you can't be certain what reserved subnets are used in a given network and you absolutely need a static ip for some reason.

        At least that's the conclusion I've arrived at at some point, but I don't remember what was the exact use case anymore.

        However there are still several global IPv4 ranges that are not local reserved ranges but are effectively reserved and you could use them if you really want to without any issues.

    It's a shame that ICANN did get so greedy and put everyone at risk.

    Having internal domain names owned by some guy on the internet has already compromised multiple corporate networks. See the talk from this guy:

    • stackskipton 21 minutes ago
      As former AD person and dealing with that several companies, the recommendation for internal network DNS has long been subdomain.company.com that is not on public internet.

      Even today when setting up greenfield networks, I generally use internal.company.com. It also lets you get public trusted SSL certificates so you don't have to deal with internal PKI.

      • Faelian2 1 minute ago
        `.internal` and `.local` are safe and won't be used in the future. There are reserved for internal networks
    • john_strinlai 25 minutes ago
      im not super keen on all of these gTLDs, but anyone choosing to use .lan should have been aware of the risks of using an unofficial/unreserved domain.

      at the very least, the .dev stuff should have had people second-guessing their usage of unreserved domains.

      • gchamonlive 23 minutes ago
        Pihole here will still serve .lan internal domains. Anyone that registers .lan globally is the one of reserving a culturally busy domain that was unreserved before.
      • delecti 18 minutes ago
        Eh, maybe someone spinning up a brand new environment using it in 2026 should have known better. But you don't have to go that far back to reach a point where the current list of gTLDs would make .lan feel safe.
        • john_strinlai 15 minutes ago
          >But you don't have to go that far back to reach a point where the current list of gTLDs would make .lan feel safe.

          throughout most of my career, there was no unreserved domain that felt safe. but especially after .dev.

  • ectospheno 1 minute ago
    The .lan domain has been on an rpz blocklist along with several other commonly used names in my networks for quite some time. I have no plans for that domain to ever successfully resolve regardless of whether or not it goes live.

    This is a security issue for many devices. What could possibly go wrong overriding a tld used for internal networking....
    • jeroenhd 37 minutes ago
      You would hope someone would finally learn after .dev and .local started getting used.
      • irusensei 29 minutes ago
        RFC 6762 reserves the .local. TLD for Multicast DNS. There are no reservations for .lan. so something like home.arpa. should be used instead.
        • procone 22 minutes ago
          router.home vs router.home.arpa

          .home.arpa is so clunky. Why do I have to put the acronym of a US military project in my domain to access resources on my own local network?

          Yes, I know that organization was central to the development of the l Internet, but it's not relevant as a domain 40 years later.

          • 0x457 4 minutes ago
            I just bought mysefl a '.casa' domain, got wildcard cert for it from lets encrypt and haven't bothered with any of these. Downside, if internet goes down resolver stops, but thats why I have local NS mirror and all DNS queries go through my resolver.
          • irusensei 13 minutes ago
            You can buy a cheap domain to make sure no one else uses it and just roll it on your lan. Throw some DNS ACME challenges and you have valid certificates too.
            • procone 7 minutes ago
              Why should I have to purchase something (yearly subscription, mind) in order to access something that is potentially half a meter away?

              This is not how anything should work.

      What could go wrong using tlds that were not explicitly reserved for internal use?
      • alerighi 35 minutes ago
        Beside the fact that was standard or not it made sense to use .lan domain for local devices, and a lot of router sold were configured with that domain for resolving local network hosts.

        To me is a very bad idea to implement this proposal, it should instead be standardized and reserved for internal usage as a fix. There were even RFC like https://www.rfc-editor.org/info/rfc6762/#appendix-G that suggested their usage for local devices in a network.

        What is the point of selling the .lan domain, except for making money at the expense of a security risk for millions of networks that already use that domain for internal hosts?

        BTW to me there was never any sense to add new TLD domain despite country code. They decided to render internet less secure, by giving scammers infinite TLD to register they scam domain like "apple.lan", with the sole purpose of making for them easy money.

    • davidcollantes 37 minutes ago
      Indeed. It akin to an application for a .local TLD.
      • john_strinlai 36 minutes ago
        >It akin to an application for a .local TLD.

        it is not, as .local is designated as a special-use domain name and .lan is not.

        • gertrunde 5 minutes ago
          While you're not wrong, I suspect that .lan sees more real world usage than .local

          It may not be an official standard, but it does have some weight as a de-facto standard.

          I've tried briefly to try and find some numbers to back that up, but can't find much beyond apple's bonjour vs consumer routers - although I've seen companies with AD domains using .lan as well. (Although, I've also seen companies using 1.0.0.0/8 for their internal addressing...)

          • john_strinlai 4 minutes ago
            it definitely gets used, and i hope that the application is denied, but i also hope this is another wake up call for people that pick unreserved domains.
    • seanw444 42 minutes ago

    Also see a .bldg application, which also might conflict with some legacy naming schemes.

    I'm out of the loop on this, can someone explain who this is and why this is bad?
  • 0x0 18 minutes ago
    I've been using a single letter "fake" tld for my internal LAN DNS zone. Looks like ICANN requires 3+ letters in tld applications, so hopefully should be safe for quite a while.
  • dijit 21 minutes ago
    I'm still seething about `.dev`.

    For those not in the know, Google lobbied ICANN to get the name and in their application they stated (repeatedly) that the intent was to buy it so that it could be reserved; as .dev was already used by developers and if someone bought it for commercial purposes it would harm the developer community.[0]

    .... they then proceeded to start selling them.

    Leading to all kinds of issues, the exact issues that they raised...

  • procone 29 minutes ago
    gTLDs were a mistake. I say that as an owner of several domains with gTLDs.

    There's almost no value.

    Large businesses almost never use them. The potential for scams / phish / etc are now limitless.

  • p1mrx 30 minutes ago
    When ICANN reserved .internal a couple years ago, I was saying they should just flip and truncate it to .lan(retni) so everyone's happy.
  • deno 28 minutes ago
    Why would you even want something like “lan” as a global TLD? Does it mean something else than the obvious?

    Fortunately there’s no need to speculate as the application explains this clearly:

      AGB Q118: What is the meaning/definition of the applied-for gTLD string?
      Answer: Lan commonly refers to a broadly recognized term used across a wide range of contexts.
    • notpushkin 5 minutes ago
      Man, my whole life I’ve identified with, related to, and wished to finally just be associated with “the concept represented by the applied-for string”!

      The applicant appears to be an agglomeration of LLCs and legal diversions to hide responsible parties. It does lead me to assumptions about their motivations, whomever they may be.

      Source: the application refers to multiple layers of LLC ownership, and the responsible parties listed are general counsels at some IP financialization company, "Identity Digital"
