the :: is ipv6 notation for "all zeroes" So in that UI enter 2606 : 4700 : 4700 : 0 : 0 : 0 : 0 : 1111

If you don't want to visualise this yourself you can use an online tool like https://dnschecker.org/ipv6-expand.php

DNS Checker

IPv6 Expand - Expand IPv6 and Convert to Un-Compressed Form

IPv6 Expand tool converts the short or compressed form of IPv6 Address to a Full IPv6 Address. This tool adds empty octets and full notations to the compressed IPv6 Address in which they were removed, this process converts IP to its original form.

No problem - I don't like when companies force data entry fields like this because it assumes you know how ipv6 works :)
