Summary
Webster University
education research infrastructure
The netname begins with the word for a block of addresses, which is the one thing a netname never needs to say.
What it's used for
- A university's network. One IPv4 prefix announced from the United States, no IPv6, two thousand and forty-eight addresses, through four observed BGP neighbours.
Notable
- The netname is six letters meaning a block of addresses, a hyphen, and then the university's name run together with its own word shortened. The first half is redundant with the field it sits in.
- The AS handle keeps only the first word, so the handle is shorter than the netname by everything the netname added.
- The whole announcement is one contiguous block, small by campus standards, registered to the university with no extra contact.
- Four observed neighbours for two thousand addresses is a lot of upstreams for a holding this size.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The block-of-addresses prefix was a convention from an era when registry records held several kinds of object and the name had to say which. The objects were separated long ago; the prefix stayed on the records that already had it.
- A university with campuses in many places buys connectivity in many places, which is the readable explanation for four upstreams on a small block. The routing is spread wider than the addressing.
- Two thousand addresses is a modern-sized allocation rather than a legacy one. Nothing here was handed out by the block.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
