Summary

Hutchison Drei Austria (UTA)

Austria · AI-generated

isp mobile eyeball legacy

Hutchison Drei Austria GmbH (UTA-AS) — the network of "Drei", Austria's Hutchison-owned mobile and fixed operator. The UTA handle is a leftover from UTA Telekom, the alternative carrier that passed through Tele2 Austria before Drei absorbed it.

What it's used for

  • Subscriber access for Drei's Austrian customers. The bulk of the sampled address space resolves as IP-ADDR.wireless.dyn.drei.com — dynamic mobile and fixed-wireless pools — with a smaller slice of IP-ADDR.dsl.dyn.drei.com fixed broadband.

Notable

  • An "eyeball" network: these are end-user devices, not servers, and the addresses are mostly dynamic.
  • A handle trap. UTA-AS reads like the old UTA business/fixed carrier, but the rDNS shows the AS today carries Drei's consumer access traffic, predominantly wireless.

Interesting

  • Austria's fixed-alternative carriers consolidated hard: UTA into Tele2, Tele2 into Drei. The AS number and its handle survived all of it, which is why a mobile-first operator answers to a fixed-line carrier's name.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
