Today we’ve launched a new domain for Dynamic DNS which will be used for all new networks going forward and all existing networks can opt-in to using it.
The new domain is 2my.network.
From your Dashboard go to Advanced / Info
For existing networks you’ll see your current hostname, new sites will have a Create button.
Click the Edit button on the right and you can change the public portion of the hostname, if you do so on any existing domain that ends in
dnsthingy.com it will also automatically be updated to the new domain
