You can capture without the computer having its own IP.

I'm doing this myself on a Linux machine using the tcpdump utility (just to grab the packets for later analysis) but you can do it directly from wireshark too of course.

I'd like to use Ethereal/Wireshark at one of my customer sites and 
need some help. Specifically I need to setup a packet capture on a public segment with no free IPs. 
Basically, whether the capturing computer has to have an IP address on 
the same segment as the device connected to the Internet, the server 
(Novell) in this case, or whether it can capture all traffic (possibly 
as long as at least some aspects of the IP setup are similar)
