Which version of PIX are you running? For the purposes of picking one to
describe, I'm looking at the 7.2 documentation. You can find PIX command
references for other software versions here:

For logging *PIX interface IP addresses* rather than interface hostnames
when you are using syslog, you can use the "logging device-id" command,
which lets you specify whether you want hostnames or IP addresses:

tml#wp1692412

I'm not sure there's a way to disable hostname lookup *just* for PIX traffic
logs. If you want, you can disable hostname lookup on a per interface basis,
for all activity on the device:

no dns domain-lookup <interface_name>

http://www.cisco.com/en/US/docs/security/asa/asa72/command/reference/d2_72.h
tml#wp1777563

or http://tinyurl.com/22zd8f

I wouldn't be surprised if these commands are highly dependent on software
version, so if you're not on 7.2, look for equivalents in the appropriate
documentation.
