Summary

ELXSI

Germany · AI-generated

residential isp germany ppp

The AS handle ELXSI-AS is held by Martin Kluge.

What it's used for

  • The address space carries residential access traffic, evidenced by reverse DNS entries such as customer-254138.ppp.as35292.net and dhcp0.elxsi.de.
  • The network announces 4096 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are listed as Martin Kluge, matching the AS holder name.
  • The address inventory consists of five distinct IPv4 blocks, including a /21 and several smaller /22, /23, and /24 prefixes, all registered under the netname ELXSI-NET.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-05, 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
