AS14426 — MACEWAN

AS14426 announces 6 IPv4 prefixes covering 9,728 addresses and 0 IPv6 prefixes.

About this network

Five netnames numbered one through five, on six blocks, with nothing else on the record at all.

What it's used for

• A university's network. 9,728 addresses across six IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• The blocks carry MACEWAN1 through MACEWAN5, all registered to Grant MacEwan University with a Network Operations Center contact.
• Two announcements share MACEWAN5, so five labels cover six prefixes.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Numbering blocks in the order they were obtained turns the registry into a timeline. The /19 came first, then three /24s from ranges issued in the early nineties, then the pair that share the fifth label. A campus grew one allocation at a time and wrote down the order without meaning to.
• Two announcements under one netname is an allocation split for routing after it was registered as a whole. The label describes what was received; the routing describes what is in use.
• Not one of eighteen addresses answered a reverse lookup. Universities usually name everything, so either the zone lives with an upstream that never delegated it back, or the campus decided its addresses do not need public names.
• Two neighbours and no IPv6 on a network of nearly ten thousand addresses is a conservative arrangement. Everything here has been working for a long time and nobody has needed to change it.
