slow lookup of names (resolution¿?)


Hi people, I have problems with configuration, SuSe 10 here.

Before there only was a router, and the navigation was good.

Now the configuration have a router and a switch and I have somewhat slow connection.

For example when I put in ff google.com.mx in the bar at the botton it stop for a while (10 secs) saying something like "looking up google.com.mx...", after the connection goes fine, afte4r some minutes when it need again look up, it is a stop "looking up xxx...", by the way, when Im downloading something after the look up, the speed of the transference is constant 50Kb/s.

If you need to know other configuration or running of a command say me, or more in depth info.

Code:
rea@linux:~> time host google.com.mx
google.com.mx has address 216.239.37.99
google.com.mx has address 216.239.57.99
google.com.mx has address 216.239.39.99
google.com.mx mail is handled by 10 smtp1.google.com.
google.com.mx mail is handled by 20 smtp2.google.com.
google.com.mx mail is handled by 30 smtp3.google.com.

real    0m3.699s
user    0m0.008s
sys     0m0.024s
rea@linux:~> time ping google.com.mx -c 3
PING google.com.mx (216.239.39.99) 56(84) bytes of data.
64 bytes from 216.239.39.99: icmp_seq=1 ttl=235 time=98.6 ms
64 bytes from 216.239.39.99: icmp_seq=2 ttl=236 time=99.2 ms
64 bytes from 216.239.39.99: icmp_seq=3 ttl=235 time=98.8 ms

--- google.com.mx ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 6193ms
rtt min/avg/max/mdev = 98.631/98.882/99.204/0.350 ms

real    0m16.341s
user    0m0.008s
sys     0m0.008s
Code:
rea@linux:~> cat /etc/resolv.conf
nameserver 192.168.1.254
nameserver 192.168.254.254
search site

I have read something about ipv6, but I dont understand why before the navigation was fast, andnow no.

Slow "looking up of sites" usually means a bad primary DNS server listing. This would be the 192.168.1.254 in your resolv.conf, are you sure a DNS server exists at this address? If not then all name lookups will wait for a timeout trying to get to that nameserver before going to the DNS server that does exist at 192.168.254.254
