I re-fell in love with :g/ when I discovered norm f{char}. In the following sample text, say you want to delete the two words between the name and the IP address, and "has address" isn't spelled the consistently throughout (preventing us from using :s/has address//). You can do this:

:g/\d\+\.\d\+\.\d\+\.\d\+/norm f w2dw

The above command changes this:

yahoo.com has address 216.109.112.135
yahoo.com is address 66.94.234.13
google.com is IP 216.239.37.99
google.com has IP 216.239.57.99
google.com has address 216.239.39.99
msn.com has address 207.68.172.246
vhost.sourceforge.net is address 66.35.250.210

to this:

yahoo.com 216.109.112.135
yahoo.com 66.94.234.13
google.com 216.239.37.99
google.com 216.239.57.99
google.com 216.239.39.99
msn.com 207.68.172.246
vhost.sourceforge.net 66.35.250.210

Or you could use :s

:%s/\s\zs\w\+\s\+\w\+//

Actually, this would work ':%g//norm f w2df ', assuming that the columns are separated by spaces instead of tabs.
