How do custom domains work?

If you have a domain registered elsewhere and want to use it on an upgraded site please point your domain to Tank as follows.

Point the a-record of the domain to us

Request your ISP to point the a-records (with and without the ‘www’) of your domain to

Another way to put it is to map the hostnames @ and www to the destination

(Please note this option means your email will remain entirely intact and stay with your current ISP.)
