Selection of a default prefix is easy. Here are the steps. 4. Keeping in mind 4.1 Prefixes longer than somewhere around /48 to /56 may be excluded from the global routing table4.1a Prefix cutouts of any size (including /48) from inside your /32 or larger block may be excluded from the global routing table. Folks who are multihomed and thus need to advertise their own block with BGP should be referred to ARIN for a direct assignment. Folks who aren't multihomed, well, until given evidence otherwise I claim there are no single-homed entities who will use 65,000 LANs, let alone more.============================================= This brings up another interesting question... We operate Two separate networks in two geographical locations (Two ASN), we have a single /32 allocation from ARIN. Question: Should we be asking ARIN for another /32 so that each network has it's own /32 or should be break out the /32 into /36 and use these in each of the geographies ?
Depends on your needs… Either is a viable solution, depending on your circumstances. ARIN has an MDN policy which would facilitate your acquisition of a second /32. Owen
