Well, if you're looking to extract the IP & mask you could use a
regEx. They're not tooooo bad....
If it's only that line that you're extracting, and it's format doesn't change
import re
pattern='ifconfig_fxp0="inet (?P<ip>*.?) netmask (?P<mask>*.?)"
reObj=re.compile(pattern, IGNORECASE)
jay = os.popen("grep ifconfig_fxp0 /etc/rc.conf").readlines()
matches=reObj.search(jay[0])
ip = matches.group('ip')
netmask =matches.group('mask') #You can then do your string splits,
whatever now.

regExs, can be your friends. If you KISS.
