It is well known that it is possible to configure a DNS server to do a "catch-all" resolving on a single subdomain level, such as
*.example.com. IN A x.x.x.x, so that
anything.example.com maps to a single IP/CNAME.
However, I need to set up an at least "level-2" wildcard sub-subdomain catch-all wildcard system so that
any.thing.example.com or better,
item.of.any.level.under.example.com will be resolved to a single IP.
Has anyone got this working?
