About this network

An early network number that did not appear in routing until a decade later.

What it's used for

• A university network. Three IPv4 prefixes announced from Saudi Arabia, no IPv6, a thousand two hundred addresses, through one observed BGP neighbour.

Notable

• The number was allocated in an early block of the numbering space, but the routing history first records it more than ten years after its neighbours in that range appeared.
• All three blocks share one netname, the institution's initials and a digit, with nothing to distinguish them from each other.
• The registrant field names the university and its technology deanship, but drops a word from the title that the holder record includes, so the two spellings of the same body differ.
• Two of the three blocks are adjacent in the address space and could be announced as fewer routes.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• A low number appearing in routing that late means it was assigned, unused or used privately, and brought into service much later. The number is older than the network.
• One netname across three blocks is the registry equivalent of leaving a form field on its default. It makes the blocks indistinguishable in any tool that groups by name.
• A thousand addresses and one upstream, with no IPv6, is a small footprint for an institution of this size, which usually means most of the campus sits behind translation.
