Adding a custom domain allows you to have a domain name attached to your web site. So if you had a domain like catsknitting.com, you could have it point to your Neocities site. If you don't have the domain yet, you will have to purchase a domain name from a registrar like Namecheap first.
<% if current_site.custom_domain_available? %>We will be using catsknitting.com for the examples below.
First, you need to add an "A record" to point your root domain (sometimes shown with an @ symbol) (catsknitting.com) to the following IP address:
198.51.233.1
Now you need to add an "AAAA record" that also points to your root domain. This is for IPv6 support. Use this address for the AAAA record:
2620:2:6000::bad:dab:cafe
Add the domain name to the box below (just the catsknitting.com, don't add any subdomains), and your domain should come online within 5 minutes!
