Comment on What path does data take when connecting to a domain at my address?
lyralycan@sh.itjust.works 1 week agoAlso if you have your own net filter like PiHole or AdGuard Home with DNS rewrites set up, and you use it as a DNS server in WiFi settings, then it works a small bit differently. A public IP and NAT routing is never needed, as the device contacts the DNS server via the router Access Point, and the DNS server translates the service’s FQDN into its internal IP. Aside from that, provided everything is set up correctly, all actual data packets go from device ←→ router ←→ service

I had issues with that recently, I had a few of my internal services set to resolve internally, but pihole was making a mess of them and returning IPv6 addresses in addition to the IPv4 internal addresses. And then browsers would try use the broken ipv6 address and fail. I just happily rely on hairpinning now, it hardly makes a difference in the scheme of things.
