DNS Requirements

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

DNS Configuration

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

Examples

wiki.jb-vpn.uk → 87.106.61.62 werbs-wiki.jb-vpn.uk → 87.106.61.62 dsm.jb-vpn.uk → 87.106.61.62 plex.jb-vpn.uk → 87.106.61.62

DNS Propagation

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

Verify DNS Configuration

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

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

SSL Certificate Requirements

Before obtaining an SSL certificate, ensure:

DNS A record is created

DNS has propagated (can be verified with nslookup)

Port 80 is accessible (required for Let's Encrypt validation)
