Summary
VTG (Vorarlberg IT and Telecom Services)
business isp telecom
A regional IT services company announcing its own space alongside the local power utility's.
What it's used for
- IT and telecommunications services for a region of Austria. 13,312 addresses in four IPv4 prefixes, one IPv6 prefix, and 10 observed BGP neighbours.
Notable
- The largest block,
212.51.224.0/19, carries the netnameAT-VTG-19991027; the newest,185.210.12.0/22, isAT-VTG-20170626. - Two
/21s are registered asAT-VKW-NETtoillwerke vkw AG, not to the announcer. - The IPv6 announcement is
2a00:40c0::/31. - One sampled address answered, as
egvbredzfw1-gw.egv.at.
Interesting
- The utility's blocks sitting inside a services company's AS is the shape of a regional group: the power company owns the address space, the IT arm runs the network, and the registry keeps both facts. Municipal and regional utilities were often the first organisations in their area with fibre in the ground, and the internet business grew out of that.
fw1-gwin a reverse name is a firewall acting as a gateway, numbered because there is more than one. Reverse DNS that names equipment by role rather than by address is written by hand, which means somebody decided these particular hosts were worth naming.- A
/31is an odd size for IPv6. It does not fall on a 4-bit boundary, so its reverse zone cannot be delegated as one piece — it takes two/32-sized zones to cover. - The netname dates it to 27 October 1999, one day off a batch date seen elsewhere in this range.

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 1,771 prefixes, as published 2026-10-15. 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.
