DNS troubles?

Hi, I've been noticing more lag lately when browsing pages. I think I may have some issue with DNS.

When I do a traceroute, it hangs for about 7 seconds, then this is what I get:

martron@compewter:~$ sudo tracert teksavvy.com
traceroute to teksavvy.com (206.248.147.105), 30 hops max, 60 byte packets
1 206.248.154.104 (206.248.154.104) 14.640 ms 15.565 ms *
2 * * *
3 * * *
4 * * *
5 * * *
6 * 206-248-147-105.dsl.teksavvy.com (206.248.147.105) 21.945 ms 23.573 ms

My d-link router is showing:
gateway: 206.248.154.104
primary dns: 206.248.154.22
secondary: 206.248.154.170

The browsing lag isn't horrible and I can live with it, but it feels like something's up. Thoughts?

post in direct forum or call teksavvy support or use some other nameservers and see if that fixes the problem (i.e opendns.com's servers)

Slight geekish note, no need to sudo when doing a traceroute :)

Depends on the implementation of traceroute and if it needs to access raw sockets

If yes, and traceroute is not setuid root then you'll need to su or sudo

I'm having some HUGE issue. My connection is going up and down..

Router, Computer are fine. Just my modem connection.

Yeah, ubuntu demands that you run tracert as root. Otherwise it says "The specified type of tracerouting is allowed for superuser only".

Anyway, I think I may try a different modem I have lying around. Just mess around with all the links in my chain first.

So I've been monitoring this for the last while and have some observations.

When browsing is abnormally slow, my traceroute to teksavvy.com looks like above with a number of unreachable hops (* * *). I can resolve this by resetting the connection to teksavvy and getting a new ip.

When I get a new ip, things are snappy again and my traceroute looks more normal:

traceroute to teksavvy.com (206.248.147.105), 30 hops max, 60 byte packets
1 lo-100.lns02.tor.packetflow.ca (206.248.154.122) 12.586 ms 13.519 ms 16.498 ms
2 2120.ge-1-4.erx02.tor.packetflow.ca (69.196.136.69) 19.453 ms 21.418 ms 23.410 ms
3 ssg.prem.pppoe.ca (206.248.154.204) 32.319 ms 35.266 ms 36.230 ms
4 206-248-147-105.dsl.teksavvy.com (206.248.147.105) 37.149 ms 41.082 ms 43.043 ms

Maybe some IPs are timing out on the bell network? Maybe my modem is the problem? Gonna keep making observations. Obviously this isn't a big problem.
