I’ve wanted to install pihole so I can access my machines via DNS, currently I have names for my machines in my /etc/hosts files across some of my machines, but that means that I have to copy the configuration to each machine independently which is not ideal.

I’ve seen some popular options for top-level domain in local environments are *.box or *.local.

I would like to use something more original and just wanted to know what you guys use to give me some ideas.

    RFC 6762 defines the TLDs you can use safely in a local-only context:

    *.intranet
    *.internal
    *.private
    *.corp
    *.home
    *.lan

    Be a selfhosting rebel, but stick to the RFCs!

        https is not a problem. But you’ll need an internal CA and distributed its certificate to your hosts’ trust store.

      I use *.home.mydomain for publicly-accessible IPs (IPv6 addresses plus anything that I’ve port forwarded so it’s accessible externally) and *.int.mydomain for internal IPv4 addresses.

    I have a registered domain and my lan domain is “int.registereddomain.com”. This way I can use letsencrypt etc for my internal hosts (*.int.registereddomain.com via dns challenge). The actual dns for my internal domain itself is not public but static records in pihole.

      Can I ask why this is done over something like hosting your own certificate authority? I’m quite new to all this DNS stuff

        If you own your own domain, the lifecycle toolchain to request, renew, deliver certs around a variety of cert authorities (letsencrypt is a popular one) makes it really easy, along with not having to worry about hosting an internal CA but more importantly dealing with distributing root certs to client devices that would need to trust it.

        I’ve used https://github.com/acmesh-official/acme.sh as a one-off for updating my Synology’s https certificate (two lines - one fetch, one deploy - finishes in 20 seconds and can be cron’d to run monthly) and Caddy natively handles the entire lifecycle for me (i use cloudflare for my domain registrar which makes it both free and a snap to handle TXT challenge requests).

        Certbot is another popular one.

      I want to do this, but I have no clue how to set it up on Asustor AS6706T. I’ve got a bunch of docker apps up and running and I’d like to simplify stuff with subdomains and better ssl. The whole self signed stuff is just a whole project in itself to work right.

      I did something similar, though I’ve done a slight bifurcation-

      *.i.domain.tld -> the actual internal host/IP (internal dns is adguard)

      *.domain.tld all resolve internally using a DNS rewrite to a keepalived VIP that’s shared between a few hosts serving caddy that handle automatic wildcard cert renewals / SSL / reverse proxy.

      While I talk to things via *.domain.tld, a lot of my other services also talk to each other through this method - having some degree of reverse proxy HA was kinda necessary after introducing this sort of dependency.

      Hmm I thought when I add tls internal to my reverse proxy rule for local domains, it does not get letsencrypt certs. But when I leave it out of the Caddyfile rule, it gets reachable from outside of the local network. How do I use your recommondation? Using a .home.lab domain locally with a DNS name resolve for every single local subdomain (dashboard.home.lab, grafana.home.lab, etc) right now with a caddy managing the outside and the inside reverse proxy work

    I own both mydomain.com as well as mydomain.me. I use the *.me as my local domain and *.com for the real world.

    .box since it’s recognized as valid TLD by many devices. Never use .local it’s reserved for multicast DNS.

    “.home.arpa” for A records.

    I run my own CA and DNS, and can create vanity TLDs like: a.git, a.webmail, b.sync, etc for internal services. These are CNAMEs pointing to A records.

    .local is mDNS - and I’m using that, saves me so much hassle with split-horizon issues etc.

    I also use global DNS for local servers (AAAA records on my own domain), again, this eliminates split-horizon issues. Life is too short to deal with the hassle of running your own DNS server.

    I had problems with .local because it’s used for MDNS and too lazy to figure out how that works so now I just use lan but I also own a .com domain so I have started to use that more
