Summary

VISTEC Internet Service GmbH

Germany · AI-generated

transit isp germany

VISTEC-AS is operated by VISTEC Internet Service GmbH, a German internet service provider based in Wiesbaden.

What it's used for

  • The address space is registered under netnames DE-VISTEC-990819 and DE-VISTEC-20150413 for the main VISTEC holdings, while SVA-System-NET and DE-SVA-19980925 indicate space associated with SVA System Vertrieb Alexander GmbH.
  • With 9,728 IPv4 addresses and 3 IPv6 prefixes announced against 80 observed neighbours, the high neighbour-to-address ratio suggests a transit or peering-heavy role rather than a large-scale access network.

Notable

  • Registrants for the largest prefixes are primarily VISTEC Internet Service GmbH, though two prefixes are registered to SVA System Vertrieb Alexander GmbH, indicating a relationship or historical acquisition.
  • The inventory consists of four IPv4 prefixes and three IPv6 prefixes, with the largest block being 213.216.0.0/19.

Reputation

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.
