One liner to bulk add ipv6 addresses from a range

This guide is not complete on setting up ipv6 on cpanel rather this is one part of it.

Cpanel can be a bit of a pain if you want to assign a site a specific Ip from a range of Ipv6 addresses.

You can’t do this if you just add the one big range.

Instead, it is best to add addresses as individual /128 but who has time to sit there and add them?

That is where a one-liner like this can be handy.

Note: You will want to replace Prefix in the command before you run the below command.

for i in {1..500}; do whmapi1 --output=jsonpretty ipv6\_range\_add range='Prefix::'$i'/128' name='IPv6Address'$i ; done
