There's a short list of grounds they will consider for an objection, and none of them are applicable here. Paraphrasing your second link, they only allow:
- "String Confusion" -- looks or sounds like an existing (approved or being applied for) gTLD. Must be filed by whoever owns (or is applying for) that gTLD.
- "Legal Rights" -- someone else owns a trademark this would violate. Must be filed by whoever's legal rights would be violated.
- "Limited Public Interest" -- the gTLD is immoral under recognized principles of international law. I have no idea when this could be applicable.
- "Community" -- An established community organization believes the group this gTLD is intended to target will object to it. This seems more like a vehicle for e.g. Little People of America to let ICANN know that ".midget" would be offensive.
Unfortunately there doesn't seem to be a way to tell ICANN that .lan has been widely used and will break things in a way they will listen to.

> Unfortunately there doesn't seem to be a way to tell ICANN that .lan has been widely used
ICANN isn't the DNS police, and lobbying them is pointless. We should campaign for open-source router projects[0], commercial hardware developers[1], DNS resolver developers, and major providers[2] to collectively designate commonly used private TLDs such as .home, .lan, .intranet, and .private as non-resolvable in public DNS.
Local resolution would continue to work, but these names would never be forwarded upstream. With sufficient adoption, we'd establish a de facto reservation and make the TLDs commercially worthless, regardless of what ICANN decides.

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!
It looks like as part of the process, they delegate the prefix in global DNS and see how much traffic it currently gets; if it gets too much it will be classified as "high-risk" which at least makes things harder. Which is to say, we want as much leakage as possible to hopefully make ICANN think twice about approving this.
and most people dont use it because its an incredibly poor name.

- it is a second-level domain, why?
- 9 characters (home.arpa) is a lot
I kind of understand the motivation, it is a "technical" domain since it doesn't represent something in the global DNS registry, so it gets the .arpa TLD. However, that's reasoning that it out of touch from normal users. Normal users don't want to be exposed to the technicalities of DNS when they enter something in the address bar, and "myserver.lan" is more meaningful than "myserver.home.arpa", and giving meaningful names is the whole point of DNS.

gavinsyancey 7 minutes ago [-]
I looked into the actual reasoning here:
- Originally, IETF specified .home, but never went through the process to add it to the list of reserved names.
- Someone applied for the .home gTLD, and while it ultimately didn't go through there was a while while it was up in the air. Due to this the homenet working group had to change gTLDs.
- They decided to switch to .homenet. However, because of DNSSEC, whatever they used would need an insecure delegation in the root zone or validating resolvers wouldn't be able to resolve it. Since IAB controls .arpa but IANNA controls the root and there was no process to ask IANNA for this, they eventually decided to use home.arpa instead.
> RFCs were originally formalization of what was being used in practice
You may be confusing it with the IETF’s policy.
In early days of the RFCs, most started out as proposals, often but not always with some existing implementation as a jumping-off point to conversation (hence the name). I no longer remember why they started to be numbered and tracked, as the process naturally preceded that.
You can verify what I say by just reading some old ones at the rfc editor site.

Then why hasn't there been a gTLD reserved for local use? The only ones that are reserved are .local and .home.arpa. .local is out, since it is entirely for use with mDNS / Bonjour.
That leaves .home.arpa, which is very awkward and only a thing since 2018 (my home network's use of .lan definitely predates this). Especially as a non US citizen. It also seemed so far that .lan was the "unofficial" gTLD to be used, since much software like OpenWRT was already using it anyway.
Either way: making .lan internet routable seems entirely unhinged to me. LAN has always been the acronym for Local Area Network. Why would anyone sane think that it is a good idea to make this into a gTLD that can be internet routable? The only way I see forward to do this justice, is to only allow RFC 1918 and IPv6 addresses that are within the assigned prefix for your router.
This seems like a worse version of allowing .zip to be a gTLD. Remember the idea of downloading something from https://github.com/[...]@evil.zip?

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.

https://www.romhack.io/wp-content/uploads/2025/10/Internal-D...
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.
at the very least, the .dev stuff should have had people second-guessing their usage of unreserved domains.
That leaves .home.arpa, which is very awkward and only a thing since 2018 (my home network's use of .lan definitely predates this). Especially as a non US citizen. It also seemed so far that .lan was the "unofficial" gTLD to be used, since much software like OpenWRT was already using it anyway.
Either way: making .lan internet routable seems entirely unhinged to me. LAN has always been the acronym for Local Area Network. Why would anyone sane think that it is a good idea to make this into a gTLD that can be internet routable? The only way I see forward to do this justice, is to only allow RFC 1918 and IPv6 addresses that are within the assigned prefix for your router.
This seems like a worse version of allowing .zip to be a gTLD. Remember the idea of downloading something from https://github.com/[...]@evil.zip?
Home.arpa exists, or buy a domain and use that. Or pick something that’s not reserved and run the risk of this happening.
.qm to .qz and .xa to .xz have always been implicitly reserved as TLDs that will never be globally-routable [0] [1], but these aren't exactly the most intuitive names so it's unsurprising that nobody uses them.
(".internal" as mentioned by the sibling comment [2] is the best choice these days, but its definition is somewhat recent.)

there is. it's .internal.

(note: i hope .lan does not get approved, but people have to understand that they are rolling dice when using unreserved names)
edit: fucking wild that this is downvoted into negatives. press the wiki link and read the first line if you don't believe me. in fact, i will quote it: "The name internal is reserved by ICANN "
That explains why I hadn't heard of this yet. My current incarnation of my internal network dates from ~april 2024.
In time we'll see articles like "Don't register a .lan domain if you want people to visit your site"
throughout most of my career, there was no unreserved domain that felt safe. but especially after .dev.
.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.
This is not how anything should work.
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.
it is not, as .local is designated as a special-use domain name and .lan is not.
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...)
Also see a .bldg application, which also might conflict with some legacy naming schemes.

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...

There's almost no value.
Large businesses almost never use them. The potential for scams / phish / etc are now limitless.
There are questions that literally say as part of the question "Choose Yes or No", so they've answered "true"...
And Q165 is fun: "Is it likely that consumers will face significant risks if domain names in the TLD(s) in the application are abused?" Answer: "No"
I'm guessing that'll end up being expensive for someone...
Fortunately there’s no need to speculate as the application explains this clearly:

ICANN Reveals 2026 Round Applications for New Generic Top-Level Domains

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"
It's monopolies like Verisign (of the .com tld) that have luxurious profits. No competition, plus they are allowed to raise their prices above inflation while their infrastructure costs go down every year.
