Using DNS server to stop local domains going through internet

Ok, thanks for relying.

I don't think its the DNS lookup that is sowing things down, I think it is
the fact that all the traffic is routed through the net rather than locally
that is causing the problem.  So a simple DNS cache is not going to solve
the problem.

I have actually set up a DNS server (bind) and got it working, that was
fun;)....well almost;(.

I have the basic thing working, just cant do the funky stuff to get
prsc.noip.me to resolve to the local server rather than the DyDNS service.

The zone (db.prsc.noip.me) I am trying to do it with looks like this.

$TTL            604800
@               IN      SOA     pluto.prsc.localhost. pi.localhost. (
                                      2         ; Serial
                                 604800         ; Refresh
                                  86400         ; Retry
                                2419200         ; Expire
                                 604800 )       ; Negative Cache TTL
;
@               IN      NS      pluto.prsc.localhost.
@               IN      A       127.0.0.1
@               IN      AAAA    ::1

; Beow are the A record addresses

prsc                    IN      A       192.168.0.50

; Below are the CNAME record addresses (aliuses) - point ot the A records

oCserver        IN      CNAME   prsc.noip.me.

But I get an unknown host error when I try to ping prsc.noip.me.
