This is intentional  to keep DNS lookups from slowing down the packet list
display even the slightest bit.

Are the hostnames that are not resolved the same every time?  Are you using a
form of Unix or Windows?  If on Unix, try looking up the hostnames with the
adnshost program (if installed on your system): adnshost <hostname>.  Do they
resolve then?
