Hello, I'm using BIND 9.3.4-P1 on Linux CentOS 5.2. I'm trying to set up a local caching DNS server but when I try to test my set-up using: dig google.com +trace I get the message: dig: couldn't get address for 'F.ROOT-SERVERS.NET': failure I'm pretty much a DNS beginner but I'd really like to understand why this is happening.
