Summary

Grant MacEwan University

Canada · AI-generated

education research infrastructure

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
