DNS resolving to 1.0.0.0
// November 27th, 2009 // guides, tech
I’ve had the most peculiar thing happened today at home. I think it’s Karmic issue since I never had this problem before.
Well what happened was, I was unable to browse the internet (Firefox and Chrome both had problems but Opera worked fine). Pinging worked. Other Windows machines didn’t have problems at all. Sudo apt-get update didn’t worked because it was looking up 1.0.0.0 for every mirrors I tried. I tried this with Firefox at first:
In address bar, type in about:config, filter for ipv6. There should be only 1 listed – network.dns.disableIPv6. Double click to change the value to true. Problems solved for Firefox.
I continued googling around and did this:
#in /etc/resolv.conf, changed nameserver to those of streamyx #previously it was 192.168.1.1 which points to my router #Generated by NetworkManager nameserver 202.188.0.133
And now everything works again. Only that if I reboot it will change back to 192.168.1.1



You may need to change the /etc/sysconfig/network entries. I woud prefer to use the OpenDNS IPs, 208.67.222.222 and 208.67.220.220
All dsl modems can be configured to get nameservers. Check yr modem manual?
Something is wrong with your DSL modem/router. Check which DNS server it points to when you are connected. Depending on make/model, you can force the IP address of the DNS server in the DSL modem/router
