Selfhosted

Oh, that's LAN - I thought you'd put ian and I was trying to get the joke. Stupid sans-serif fonts.

Use it anyway.

I switched from .local to .honk and I'm never looking back.

I was using .local, but it ran into too many conflicts with an mDNS service I host and vice versa. I switched to .lan, but I'm certainly not going to switch to .internal unless another conflict surfaces.

I've also developed a host-monitoring solution that uses mDNS, so I'm not about to break my own software. 😅

It's also second only to .com in terms of query volume in ICANN's Magnitude statistics with 980 mil vs .internal's 60 mil. Not sure if that makes it a de facto standard, but it's close.

I went with .home and so far the problems are within reason

What are you doing step-LAN?

I used to wonder why porn sites aren't required to use '.cum' instead of '.com'...

If you mean properly signed certificates (as opposed to self-signed) you'll need a domain name, and you'll need your LAN DNS server to resolve a made-up subdomain like lan.domain.com. With that you can get a wildcard Let's Encrypt certificate for *.lan.domain.com and all your https://whatever.lan.domain.com URLs will work normally in any browser (for as long as you're on the LAN).

Nothing, this is not about that.

This change gives you the guarantee that .internal domains will never be registered officially, so you can use them without the risk of your stuff breaking should ICANN ever decide to make whatever TLD you're using an official TLD.

That scenario has happened in the past, for example for users of FR!TZBox routers which use fritz.box. .box became available for purchase and someone bought fritz.box, which broke browser UIs. This could've even been used maliciously, but thankfully it wasn't.

Either ignore like I do or add a self signed cert to trusted root and use that for your services. Will work fine unless you're letting external folks access your self hosted stuff.

Try using .com for your internal network and watch the problems arise. Their choice to reserve .internal helps people avoid fqdn collisions.

Certain domain names are locally routed only. So if you use internal or local as a tld, you can just assign whatever names you want and your computer won't go looking out on the internet for them. This means you and I can both have fileserver.local as an address on our respective network without conflicting. It's the URI equivalent of 192.168.0.0/16.

YouCANN do anything you want?

But what if your name is not Ian...

Except when it doesn't. It can have issues around multicast dns.

I've had issues with .local on my Android device. Straight up doesn't work. I had to change to .lan

It just means .internal won't be relayed out on the internet, as it will be reserved for local only.
