Summary
all-connect
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.deand the netnamesDE-ACDC-20011217andDE-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.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
