What is SWIPed?
SWIP stands for Shared WHOIS Project. Int he verb usage which you get with
networking folks it means that the actual 'owner' of a larger netblock (the
receiver of the allocation) has made a note of the assignee of the netblock
in WHOIS....This tells you more specifically who is the contact for a block
of (usually NON-PORTABLE) addresses. IE if you do a whois for one of our
shared colo spaces say 204.11.244.17
If you're on your shell and have the whois client installed:
dhcp-2-206:~ mloftis$ whois 204.11.244.17
Modwest, Inc. MODWEST-HOSTING-1 (NET-204-11-244-0-1)
204.11.244.0 - 204.11.247.255
Modwest, Inc. Colocation MODWEST-COLO5-11-3 (NET-204-11-244-16-1)
204.11.244.16 - 204.11.244.31

If you ask for the specific NET record at whois.arin.net:
dhcp-2-206:~ mloftis$ whois -h whois.arin.net NET-204-11-244-16-1

This is a self-SWIP to indicate we're using this particular space (well
we're assigning individual /32's out of it.) Anything /28 or less should
be published in SWIP. Strictly speaking you don't have to publish
self-SWIPs like we do but it helps us keep track of things.
Some of our larger colo customers, those with enough network addresses of
their own receive a partial or simple SWIP unless they ask otherwise. It
basically puts them down as the one who is using the netblock but uses all
the contact information from our enclosing org information since they're
often not capable (and not even necessarily trusted) to be the contact for
abuse matters and the like. We do a lot of dedicated hosting.
Hope this clears that question up. Basically by publishing in SWIP I (as
an ISP who has my own ARIN issued IP space) can delegate authority for a
netblock, without giving that netblock away.
