About this network

Three spellings of one campus netname, and a single upstream for all of it.

What it's used for

• A university network. Four IPv4 prefixes and one IPv6 /42 announced from the United States, with a single observed BGP neighbour.

Notable

• The netnames are PSUNET-2, NETBLK-PSUNET-C and NETBLK-PSUNET: the same campus name with a numeric suffix, a type prefix and a letter suffix, and a type prefix alone.
• Every block is registered to the university itself, with no carrier and no role desk in the registrant field.
• The announced space spans a /19, a /22 and two /24 blocks from unrelated ranges, which is four separate assignments rather than one allocation.
• Twelve addresses were queried for reverse DNS and none returned a name.

Interesting

• The three netname variants are a timeline. A counter, a letter and a bare name are the marks of three different assignment eras, each following whatever convention the registry used at the time, and nothing has been rewritten since.
• One upstream for ten thousand addresses and a large IPv6 allocation is the standard university shape: a single research-and-education network carries everything, and commercial transit is reached through it rather than directly.
• A campus this size holding all of its own space, with no carrier-registered block anywhere in the record, is less common in this range than the borrowed-space arrangement most holders show.
