[netmod] 6991bis: domain-name

[Ladislav Lhotka <[e-mail]>]

Hi,

as a follow-up to my comment during the NETMOD session, I want to propose the
following update to the the inet:domain-name type. The aim is to include use
cases that are currently rejected:

- classless in-addr.arpa delegations [RFC 2317], i.e. labels like "128/26"

- wildcards [RFC 4592], e.g. "*.example.net"

OLD

    pattern
      '((([a-zA-Z0-9_]([a-zA-Z0-9\-_]){0,61})?[a-zA-Z0-9]\.)*'
    + '([a-zA-Z0-9_]([a-zA-Z0-9\-_]){0,61})?[a-zA-Z0-9]\.?)'
    + '|\.';

NEW

    pattern
      '((\*\.)?(([a-zA-Z0-9_]([a-zA-Z0-9\-/_]){0,61})?[a-zA-Z0-9]\.)*'
    + '([a-zA-Z0-9_]([a-zA-Z0-9\-/_]){0,61})?[a-zA-Z0-9]\.?)'
    + '|\.';

Lada
