Summary

Net Jump

Switzerland · AI-generated

business switzerland b2b hardware

NETJUMP is operated by Net Jump GmbH.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the reverse DNS record 254-219-243-80.netjump.ch and netnames CH-WYT-20050920 and WIFAG-NET.
  • The AS announces 4608 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small-scale business or internal corporate estate rather than a transit or access provider.

Notable

  • Registrants include NetJump GmbH and Polytype S.A., with the latter associated with the WIFAG-NET netname, suggesting historical or leased address space.
  • The inventory consists of two distinct IPv4 blocks: 80.243.208.0/20 and 195.254.144.0/23, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
