RE: Config mode questions
Yes, it is an ip4 address followed by an ip4 subnet (8 bytes).

Sorry, a co-worker just pointed out to me that I was answering a completely
different question... (even at that I typed IP4_SUBNET instead of
IP4_ADDRESS). My brain must be on vacation today :)
If your question was how do you represent the subnet and netmask using only
4 bytes, the answer is... you don't. I think Roy is fixing this in the next
rev, to be 0 or 8 bytes.

Stephane.
