This document describes DNS configuration requirements for the reverse proxy system.

For the system to work, each subdomain must have a DNS A record pointing to the VPS:

[subdomain].jb-vpn.uk → 87.106.61.62

DNS changes can take up to 48 hours to propagate, though typically much faster.

==== Check DNS resolution ====
nslookup wiki.jb-vpn.uk

== Or using dig ==
dig wiki.jb-vpn.uk +short
