AS215500 ISA
Unclassified RIPE
Summary
Isabelle Kleinheuer
individual ipv6 germany
The AS handle ISA is held by Isabelle Kleinheuer.
What it's used for
- The address space consists of a single IPv6 prefix,
2a11:f2c0:ffcd::/48, with no IPv4 addresses announced. - The network maintains 15 observed neighbours against a minimal inventory of 1 IPv6 prefix, a ratio that indicates a transit or peering role rather than a large-scale access network.
- The operator is an individual based in Germany, suggesting the traffic consists of personal or small-scale professional endpoints rather than commercial subscriber bases.
Notable
- The registry holder and the AS name
ISAalign with the individual's identity. - The address inventory is extremely small, comprising only one IPv6 block, which does not fit the profile of a traditional ISP or hosting provider.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
