ubuntu slow lookup speeds

Comcast's DNS nameservers were really slow, so I switched to Google's DNS nameservers by changing the settings in my router.

Couldn't figure out why my lookups were still really slow.

Turns out Ubuntu's Network Manager was keeping old DNS info around, causing the issue. Replacing the nameservers and marking the file as unwritable by network manager fixed it:

sudo nano /etc/resolv.conf
sudo chattr +i /etc/resolv.conf
