I can't answer this for sure but it seems lookups are not cached by
apache. However the client (XP, linux) does cache lookups. The cachetime
for positive lookups on XP is rather high (24 hours or so). If you don't
need the added flexibility of dns names, IPs are fine. If that really
makes a difference wrt performance I don't know.
