Most DNS resolvers cache entries themselves. The underlying operating system usually provides this service for all network users (meaning applications). When you run "nslookup" you are bypassing the cache.

Thanks. using the testip option worked. However, I am curiouswhere within hobbit it is pulling the DNS information from. Each of the DNS servers in /etc/resolv.conf resolves the IP properly and they are authoritative for the domain. Is there a cache which Hobbit uses first?
