Summary

WebJanssen ISP

Germany · AI-generated

isp residential germany small

The AS handle WEBJANSSEN- is held by WebJanssen ISP ltd & Co KG.

What it's used for

  • The address space carries infrastructure for a small German ISP, evidenced by the netnames WEBJANSSEN-DE-NET and WEBJANSSEN-DE-NET-2 and the reverse DNS record nagios.webjanssen.de.
  • The network announces 2048 IPv4 addresses across 2 prefixes and maintains only 1 observed neighbour, a ratio that indicates a small access or eyeball network rather than a transit provider.

Notable

  • The registrants for both announced prefixes are consistent with the AS holder, identified as WebJanssen ISP ltd & Co KG.
  • The address inventory consists of two /22 blocks, 195.140.208.0/22 and 195.225.208.0/22, with no IPv6 prefixes in the inventory.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
