[ntp:questions] refid on client differs from refid on local server

With a bit of help from Danny in commenting out restrict lines, I now have NTP 
working well with my 2 Linux servers and multiple Linux clients on the other 
machine. One small query is. The refid's on the client distro's, when running 
ntpq> pe show the original IP address, as on the website for the stratum 2 
servers, but the refid IP addresses on my server ,are different. Why is this 
so? Also the other distro I use as a server (FC1) just shows alternative 
hostnames under refid for the same servers. Admittadly FC1 is using a 
slightly earlier version of NTP. A few details below, and the relevant ntpq> 
pe outputs below that.

FC2-server is using ntp-4.2.0-7
FC1-server is using ntp-4.1.2-5
FC2-client (as an example, as I have many clients) is using ntp-4.2.0-7

This is the ntpq> pe for the FC2 server

ntpq> pe

This is the ntpq> pe for the FC2 client. One of many clients on this machine

ntpq> pe
     remote           refid      st t when poll reach   delay   offset  jitter

This is the ntpq> pe for the FC1 server, on the same machine as the FC2 
server, but showing alternative hostnames, rather than IP addresses under 
refid

ntpq> pe
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================

ntpq> pe

None of this is any big deal as NTP appears to be working very well and all my 
clocks are synched, but I would like to have an explanation to my query.
