About this network

A single block announced whole, and an AS handle carrying four digits that appear nowhere in the addresses.

What it's used for

• A university's campus network. 65,536 addresses in a single IPv4 prefix, 129.68.0.0/16, with three observed BGP neighbours and no IPv6 announced.

Notable

• The block carries the netname SJU-NET, registered to Saint Joseph's University.
• The AS handle is SJU-5600.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• The number in the handle is not part of the address space, not the AS number and not the block size. Handles are free text, and organisations reach for whatever number already identifies them internally, which is usually a street address or a department code. It means something to the person who filed it and nothing to anyone else.
• The whole range is announced as one prefix. A campus network that never had to split its announcement is one whose growth all happened behind the same door.
• Three neighbours for a single-campus university is more than the minimum. Research and teaching traffic tend to arrive over different arrangements, and a regional education network often sits alongside the commercial providers.
• The netname says NET after the initials, a habit from when a registry record described a network rather than an owner. Nothing else in the entry adds detail, and nothing answers a reverse lookup either.
