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!

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.
I hope the gTLD application gets struck down.

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.
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...
And of course the real failures are more like, only people from the Maldives can't send email to your email server, a failure with no impact.
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.
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.
This may very well end up to be determined too risky to be delegated, like .corp, .home and .mail in 2018.
Having internal domain names owned by some guy on the internet has already compromised multiple corporate networks. See the talk from this guy:
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?
there is. it's .internal.
https://en.wikipedia.org/wiki/.internal
(note: i hope .lan does not get approved, but people have to understand that they are rolling dice when using unreserved names)
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 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"
There's almost no value.
Large businesses almost never use them. The potential for scams / phish / etc are now limitless.

I'm guessing that'll end up being expensive for someone...
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.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.
