Just because I cite the IETF, LSB or other standard doesn't mean I'm talking a literal question with an answer that is the RFC, Section or other literal string as an answer. Most everything in LPI breaks down to a standard. There are countless things in LPIC-2 that rely on fundamentals in LPIC-1. We can choose to push those fundamentals into LPIC-2, or we can address it in LPIC-1. Classful subnets affect multiple things and concepts, from IETF RFC1918 (IPv4 Private Reservations) in LPIC-1 to IETF RFC2317 (Classless IPv4 Delegation) that are more LPIC-2. Why we aren't taking the 30 seconds to point out what a class A, B and C are is beyond me. I honestly think this entire thread was born out of people saying ... "Oh, that's legacy, no one needs to know those any more" ... *UNTIL* Some stupid schmuck like myself comes along and goes ... "Ummm, yes, they are actually still used." Again, 'forget' me for actually pointing out the IETF standards that very much involve understanding the Classful subnets, including those in LPIC-1. ;) -- bjs
