ACSP Suggestion 2025.4: Include IPv6 in WhoWas

Suggestion

Author: Dale Carder   
Submitted On: 09 May 2025

Description: WhoWas queries should support IPv6 prefixes.

Value to Community:

Right now the WhoWas service only supports prefix queries for IPv4 resources. We’ve recently had the case where a downstream entity’s IPv6 resource was no longer properly allocated and we wanted to dig up the previous registration details.

We should probably have feature parity between v4 and v6 for this service.
