# Domains

Add new domains

1. Add new listen inside `systemd-boot`
2. Set `AAAA` record in your DNS
3. Set `A` record in your DNS
4. Set reverse DNS for the `AAAA` record
5. Adapt your `nginx.conf` so that you have a valid `80` listen and later generate certificates for it

## IPv6

Hex (0-9, A-F)

Address = 8 blocks * 16bit = 128bit
subnet /128 = one address
subnet /112 = 65535 addresses
=> 65535 addresses _per_ block

### Addresses
Ensure that each address has a valid `AAAA` reverse DNS entry.
