 Thank you for the input. I think the "hosts" is what I am trying to do. Aliases is when a 
name is given to a particular device to make it easier for humans to read. For 
example, instead of listing a packet using its IP address, we replace the 
IP address with a human readable name i.e. "backbone_router". This makes it much 
easier to scan the packet window and to know which device created a particular 
packet. 
  
We reveiwed the documentation regarding hosts. (now 
that we know what it is called, thank you again) 
When I attempted to use the hosts definition in 
Wireshark, I defined a plain text file named "hosts" and placed it in 
c:\users\colfaxnet\appdata\roaming\wireshark. (yes, I'm 
using Vista) The path is the one listed in "help, about Wireshark, 
Folders, Personal configuration". The entries in the "hosts" file are in 
the following form: 
  
xxx.xxx.xxx.xxx backbone_router 
xxx.xxx.xxx.xxx backbone_router  (we have two 
different subnets on the same router) 
  
We only have two entries to start. We tried 
reloading the open capture file using "view, reload" and we also closed and 
reloaded Wireshark and then re-opened the capture file. Each time the packets 
containing the IP address are still listed as the IP address and not 
as "backbone_router". 
  
Is this because the capture file was created 
without the hosts file? It appears that the hosts file should be re-read when 
Wireshark is loaded or "reload" is selected from the view menu. 
  
Again, thank you for your input.
