Dear Colleagues, I am not quite sure that routing-wg@ is a right place to ask my question, but nothing more convenient came to my mind :-) I am trying to push one BIG telecom equipment vendor TAC to consider wrong situation with assignment of IP addresses like xxx.xxx.xxx.0 and xxx.xxx.xxx.255 from dynamic IP pools bigger than or equal to /24. Quick googling has not shown any STD or BCP documents, which could be used as reference, but has shown number of pages, saying something like "do not use .0 or .255 addresses, it could cause problems". Our small research has shown that some sites are not reachable from .255 and .0 addresses. Are there any published documents or strong research results which could be used as reference point to illustrate this problem existance? -- Regards, Volodymyr.
