If a user is edit a file which contain IP addresses and would like to have them marked in a special color, adding the following code in their .vimrc file will highlight instances of IP addresses in the file being edited.
syn match ipaddr /\(\(25\_[0-5]\|2\_[0-4]\_[0-9]\|\_[01]\?\_[0-9]\_[0-9]\?\)\.\)\{3\}\(25\_[0-5]\|2\_[0-4]\_[0-9]\|\_[01]\?\_[0-9]\_[0-9]\?\)/

This will highlight IP Addresses the same way identifiers are highlighted in source code files. This tip uses the following regular expression to find the address to be highlighted.
((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)
Other regular expressions can be used to find and highlight other patterns within text.
