Comment 4 for bug 174989

I don't think that's the problem because I'm sure there's nothing wrong with that server. In all the occasions I was able to register with that DNS server. I was also successful in sending a ping to that server. The only thing I could not do is navigate using Firefox. So I thought the problem had to do with the network settings and added the address to the mentioned field. In all three occasions the system got slow the minute I did this.
The problem with Firefox was the already reported problem with ipv6 which I disabled in Firefox itself. It had nothing to do with the network settings. In fact, I'm writting this post from Ubuntustudio after disabling ipv6.
Maybe there is something else that has to be done to replicate this bug (if indeed there is such bug). The only other thing I recall I did, before filling the Domain Name, was setting a static connection.
