AS16596 Universidad Autonoma del Estado de Baja California

Ten announcements, one netname, and it is the whole parent range written out as two addresses.

What it's used for

• A university's network. Ten IPv4 prefixes and one IPv6 prefix announced from Mexico, sixty-five thousand five hundred and thirty-six addresses, through two observed BGP neighbours.

Notable

• The AS handle is the university's full name, seven words with spaces, in a field that normally holds one token.
• Every block carries the same netname, and it is not a name: it is the first and last address of the entire parent range, with spaces around a hyphen. Ten blocks, one label, none of it specific to any of them.
• The blocks are that parent range cut into six different sizes and announced piece by piece.
• Ten of eighteen queried addresses answered, each built the same way: the university's initials, the last two parts of the address, then a three-letter site code, then the university's own domain.
• Three different site codes appear across the answers, so the naming distinguishes campuses where the registry distinguishes nothing.

Interesting

• The reverse zone carries what the registry lacks. One field says which of three sites an address is at; the registry says only that the university has a range.
• A range this size is an early allocation. Universities were among the first to ask, and they were given space on a scale nobody would grant now.
• Cutting one range into ten announcements is internal routing made visible. Every one of those pieces is carried worldwide so that traffic can be steered between campuses locally.
