Re: What is the lowest prefix possible and the lowest IP@
Hate to disagree with a fellow CCIE, but an 220.127.116.11/1 would be invalid. a /1 would seem to indicate that the first bit only (the 128 bit) would be the network address. RFC specifies that a network address cannot be all 0's or 1's, that is why 127.x.x.x/8 is not valid and no 0.x.x.x/8 or less is not valid.
I have not tried this, but I would guess that a /7 to summarize 18.104.22.168 and 22.214.171.124 (0000 1000 and 0000 1001 summarized to 0000 100) would be valid.
