Unable to submit wildcard ("*.example.com") A or AAAA records in dns forwarder
Closed, ResolvedPublicBUG
Actions

Description

When attempting to submit a wildcard A record, an error appears:

me@gw01# set service dns forwarding authoritative-domain example.com records a * address '10.0.10.1'

  Invalid value
  Value validation failed
  Set failed

The same happens for AAAA records.

me@gw01# set service dns forwarding authoritative-domain example.com records aaaa * address 'fc00::1'

  Invalid value
  Value validation failed
  Set failed

This is part of DNS spec and should probably be accepted.
