Summary

SHC Netzwerktechnik GmbH

Germany · AI-generated

business it-services germany

SHC is the autonomous system for SHC Netzwerktechnik GmbH, a German IT service provider.

What it's used for

  • The address space is registered under netnames like DE-SHC-20180627 and DE-SHC, with registrants consistently listed as SHC Netzwerktechnik GmbH, SHC Guardian, and SHC Abuse.
  • The AS announces 4864 IPv4 addresses across 6 prefixes and 8 IPv6 prefixes, while maintaining only 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or large-scale access provider.

Notable

  • Registrants for five of the six IPv4 prefixes align with the announcer, identified as SHC Netzwerktechnik GmbH; the prefix 109.71.26.0/23 is registered to Aixit GmbH NOC under the netname DE-HGC-20091112.
  • The inventory consists of several /22 blocks and smaller /23 and /24 allocations, alongside a diverse set of IPv6 /48 and /29 prefixes, reflecting a segmented internal corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
