Summary

Universitaetsspital Basel

Switzerland · AI-generated

hospital business switzerland internal

The AS handle USB is held by Universitaetsspital Basel.

What it's used for

  • The address space carries internal hospital network traffic, identified by the netname UHBSNET and reverse DNS entries such as net-fw-extern.usb.ch.
  • The AS announces 32,768 IPv4 addresses across 7 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications, clinical systems, and administrative endpoints for the University Hospital Basel.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing ICT; Universitaetsspital Basel; Service Netzwerk.
  • The address inventory is finely subdivided into one /18, one /19, one /20, and four /22 blocks, reflecting site-by-site or departmental segmentation within the hospital estate.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
