transit isp germany business

ASN-ACDC is operated by all-connect Data Communications GmbH.

What it's used for

  • The address space carries infrastructure and gateway services, evidenced by the reverse DNS entry ha-gw.viom-system.de and the netnames DE-ACDC-20011217 and DE-ACDC-20190528.
  • With 5120 IPv4 addresses announced across 2 prefixes and 101 observed neighbours, the high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large access network.

Notable

  • The registrants for both announced IPv4 prefixes are all-connect Data Communications GmbH, matching the AS holder.
  • The inventory consists of two distinct IPv4 blocks, 80.254.128.0/20 and 45.83.156.0/22, alongside a single IPv6 prefix, 2a00:cba0::/32.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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.
