Germany · AI-generated

isp residential germany cooperative

SIX-AS is operated by ISP Service eG.

What it's used for

  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with 7 observed neighbours, indicating a small access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for a German internet service provider that operates as a cooperative, serving members in the Stuttgart region.

Notable

  • The registrant ISP Service eG matches the AS holder, confirming consistent ownership of the address space.
  • The inventory consists of a single /24 IPv4 block and a single /48 IPv6 prefix, representing a compact and focused address allocation.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
