Strip subdomains with DNS resolver or forwarder

[ebsense]

What is discussed in Wildcard DNS entries is great, but only gets me half way to what I need. Does anyone know of a good way to do wildcard DNS with dynamic IPs?

Right now I have to do a workaround whereas *.fake.dyn.dns is redirected to an unused IP (such as 10.255.255.2 on a 10.0.0.0/24 network).
Than I have to do a NAT entry to redirect traffic destined to 10.255.255.2 to an alias of real.dyn.dns.
The problem, besides needlessly using NAT, is that with this workaround I can't redirect *.real.dyn.dns, otherwise alias for NAT would redirect it back to 10.255.255.2...

So, in summary. does anyone know of a good way to return IP of real.dyn.dns for any of it's subdomains (*.real.dyn.dns)? I really appreciate any feedback.

Thanks,
Gene

That's up to your Dynamic DNS provider. Many of them offer an option to do that, it's something you'd have to enable on their side, or in the Dynamic DNS client options.
