One obvious difference is that there is only 1 DNS server listed in the windows config. That's because I had added 2 in ubuntu trying to get better performance. > search example.com > nameserver 1.2.3.4 > nameserver 5.6.7.8 > > dig crow202.org 1.2.3.4 >> 131 ms response dig crow202.org 5.6.7.8 >> 75 ms response I'd never heard of the dig command before, and both seems to have use the 8.8.8.8 nameserver. I was hoping to check each nameserver this way, but I', not sure I'm doing it right. I looked up the command and tried using like this dig [nameserver] [record] as in dig 8.8.4.4 crow202.org, but it still seems to use the 8.8.8.8 nameserver. dig crow202.org 8.8.8.8 >> 49 ms > ...then can you do "dig crow202.org 1.2.3.4" and "dig crow202.org 5.6.7.8" > and > get fast responses from both?
