Assumptions needed to get the same tcpdump output on different systems?

["Latha G" <lathajee () gmail com>]

Hi all,

Cann't we expect the output of tcpdump on different systems for the same
input file
to be same?
I am not getting the same output, in the sense it was differencing at the
hostnames..I suppose the problem might be DNS lookups,
one was using and the other one not.
Whether the both systems has to be DNS enabled or disabled?
Is this assumption is needed to get the same output?
Like wise , are there any other assumptions ? or it is impossible to get the
same output on different systems?

Thanks in advance.
