I have an ADSL modem that allocates IP numbers by DHCP to machines in  
my LAN including
Each machine is told to use my ISP nameservers

when i connect from that machine  inside my home LAN, it  
is identified (for example when running who on the other machine) as  
www.irun.net.au. which according to whois, belongs to my ISP.

jim-watsons-computer:~ jim$ ping www.irun.net.au
PING www.irun.net.au ( 56 data bytes
64 bytes from icmp_seq=0 ttl=64 time=0.720 ms

If i ping www.irun.net.au from the host ( then it pings  
itself, i think?
PING www.irun.net.au ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=64 time=0.173 ms

external pings take much longer :p

jim-watsons-computer:~ jim$ ping www.netspeed.com.au
PING www.netspeed.com.au ( 56 data bytes
64 bytes from icmp_seq=0 ttl=125 time=11.429 ms

Is that something wrong in my side, or at the ISP? This is a  
nuisance, but is it a problem too?
