    We use .lh, short for localhost. For local network services I use service discovery and .local. And for internal stuff we just use a subdomain of our domain.

          German router and network products company AVM learned the hard way that this is a bad idea. They use fritz.box for their router interface page and it was great until tld .box became publicly available and somebody registered fritz.box.

          Having a reserved local/internal only tld is really great to prevent such issues.

            I agree that this is a good idea, but I wanted to add that if someone owns a domain already, they can also use that internally without issue.

            If you own a domain and use Let’s Encrypt for a star cert, you can have nice, well secured internal applications on your network with trusted certificates.

              That is great when using only RFC 1918 IPv4 addresses in the network, but as soon as IPv6 is added to the mix all those internal only network resources can becomes easy publicly available and announced. Yes, this can be prevented with firewalling but it should be considered.

          Sure, you can do whatever you want. You could even use non-rfc1918 addresses and nobody can stop you. It’s just not always a great idea for your own network’s functionality and security. You can use an unregistered TLD if you want, but it’s worth knowing that when people and companies did that in the past, and the TLD was later registered, things didn’t turn out well for them. You wouldn’t expect .foo to be a TLD, right? And it wasn’t, until it was.

      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.

      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).

        Right, main point of my comment is that .internal is harder to use that it immediately sounds. I don’t even know how to install a new CA root into Android Firefox. Maybe there is a way to do it, but it is pretty limited compared to the desktop version.

          You can’t install a root CA in Firefox for android.

          You have to install the cert in android and set Firefox to use the android truststore.

          You have to go in Firefox settings>about Firefox and tap the Firefox logo for a few times. You then have a hidden menu where you can set Firefox to not use its internal trust store.

          You then have to live with a permanent warning in androids quick setting that your traffic might be captured because of the root ca you installed.

          It does work, but it sucks.

          You do not have to install a root CA if you use let’s encrypt, their root certificate is trusted by any system and your requested wildcard Certificate is trusted via chain of trust

            That’s if you have a regular domain instead of.internal unless I’m mixing something. Topic of thread is .internal as if it were something new. Using a regular domain and public CA has always been possible.

          This is not a new problem, .internal is just a new gimmick but people have been using .lan and whatnot for ages.

          Certificates are a web-specific problem but there’s more to intranets than HTTPS. All devices on my network get a .lan name but not all of them run a web app.

          What if I told you, businesses routinely do this to their own machines in order to make a deliberate MitM attack to log what their employees do?

          In this case, it’d be a really targetted attack to break into their locally hosted server, to steal the CA key, and also install a forced VPN/reroute in order to service up MitM attacks or similar. And to what end? Maybe if you’re a billionaire, I’d suggest not doing this. Otherwise, I’d wonder why you’d (as in the average user) be the target of someone that would need to spend a lot of time and money doing the reconnaissance needed to break in to do anything bad.

            I’m talking about home hosting and private keys. Not businesses with people whose full time job is to make sure everything runs fine.
            I’m a nobody and I regularly have people/bots testing my router. I’m not monitoring my whole setup yet and if someone gets in I would probably not notice until it’s too late.
            So hosting my own CA is a hassle and a security risk I’m not willing to put work into.

            For self hosting at least, having your own CA is a pain in the ass to make sure everything is safe and that nobody except you has access to your CA root key.
            I’m not saying it’s not doable, but it’s definitely a lot of work and potentially a big security risk if you’re not 100% certain of what you’re doing.

              Just use only VPN to access your services behind the reverse proxy, if you want prevent unauthorised connections.

              CA certificates are not here to prevent someone accessing a site, they are here, so that you can be sure, that the server you are talking to is really the one belonging to the domain you entered and to establish a tunnel in order to send the API calls (html, css, javascript etc.) and answers encrypted.

                That’s the problem, if anyone somehow gets your root CA key, your encryption is pretty much gone and they can sign whatever they want with your CA.
                It’s a lot of work to make sure it’s safe in a home setup.

                  You can just issue new certificates one per year, and otherwise keep your personal root CA encrypted. If someone is into your system to the point they can get the key as you use it, there are bigger things to worry about than them impersonating your own services to you.

      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.

      Quite literally my first thought. Great, but I can’t issue certs against that.

      One of the major reasons I have a domain name is so that I can issue certs that just work against any and all devices. For resources on my network. Home or work, some thing.

      To folks recommending a private CA, that’s a quick way to some serious frustration. For some arguably good reasons. On some devices I could easily add a CA to, others are annoying or downright bullshit, and yet others are pretty much impossible. Then that last set that’s the most persnickety, guests, where it’d be downright rude!

      Being able to issue public certs is easily is great! I don’t use .local much because if it’s worth naming, it’s worth securing.

      I found options like .local and now .internal way too long for my private stuff. So I managed to get a two-letter domain from some obscure TLD and with Cloudflare as DNS I can use Caddy to get Let’s Encrypt certs for hosts that resolve to 10.0.0.0/8 IPs. Caddy has plugins for other DNS providers, if you don’t want to go with Cloudflare.

          It’s a domain with hosts that all resolve to private IP addresses. I don’t care if someone manages to see hosts like vaultwarden, cloud, docs or photos through enumeration if they all resolve to 10.0.0.0/8 addresses. Setting up a private resolver and private PKI is just too much of a bother.

      @solrize @thehatfox get a free wildcard cert for your domain and use it just like any other. nothing new, nothing different. I have those running on LAN-only hosts behind a firewall and NAT with no port punching or UpNP or any ingress possible.

      if you don’t want to run a private CA with automated cert distribution (also simple with ansible or a few tens of LOC in shell or python), the LetsEncrypt is trivial and costs nothing – still requires one to load the cert and key onto a server though, which is 2/3 of the work vs private CA cert management.

      Maybe browsers could be configured to automatically accept the first certificate they see for a given .internal domain, and then raise a warning if it ever changes, probably with a special banner to teach the user what an .internal name means the first time they see one
