Unclassified RIPE
Summary
Nicola von Thadden
transit enterprise germany
VT-IT is operated by Nicola von Thadden.
What it's used for
- The address space is registered under the netname
DE-NVT-20191107with registrant Nicola von Thadden. - The AS announces 768 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 112 observed neighbours.
- This high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large access network.
- Traffic from this AS consists of enterprise internet, cloud, and voice services for customers in four German states, including critical infrastructure.
Notable
- The RDAP registrants for all announced prefixes match the AS holder, Nicola von Thadden.
- The address inventory is small and finely subdivided into three /24 blocks, consistent with an internal corporate estate or specific service segment rather than a broad residential ISP footprint.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
