Cannot resolve DNS on first attempt

$

Hi,

I've been having a strange problem at home. This happens only in Fedora. I tried with other linux distros (and other OSes) and they work, so I assume it's something in the network settings... Also, this has been going on for a few releases, it's not only with F18 that I observed it.

Here we go.

Whenever I try to do *anything* the DNS seems to not work on the first try, but always in the second attempt. Example:

Code:

[christos@xamenos] ~ $ traceroute www.google.com
www.google.com: Name or service not known
Cannot handle "host" cmdline arg `www.google.com' on position 1 (argc 1)
[christos@xamenos] ~ $ traceroute www.google.com
traceroute to www.google.com (173.194.67.106), 30 hops max, 60 byte packets

If I do this fast enough only then the second attempt works. Otherwise if I let some time pass by then again it fails on the first try. This is also happening with webpages. Firefox only opens google after reloading the page etc.

This is not site- or protocol-specific , it happens with ALL connections. SSH,FTP,WWW...

And it happens only from home and my specific provider. Other friends have the same provider/router and have the same problems (I live in France and I have France Telecom as my ISP).

I tried specifying DNS servers in the IPV4 settings of NM and disabling IPV6 just in case there was something going on there, but the problem is still there.

Any suggestions where to look next?
