[hobbit] Changed IP address

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 curious
where 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?
