[cs615asa] Can we assume ip address are always legal?

[Yanqiao Zhan]

Hi friends,
Can we assume that the ip address, mac address and netmasks in "ifconfig
-a" output are always legal? In other word, we don't need to judge whether
an ip address is in 0.0.0.0~255.255.255.255 or not, but simply say the
address match the pattern {[0-9]{3}.}{3}(0-9){3} ? Though such pattern is
quite straightforward.

Thanks,
Yanqiao
