Summary

Online Travel AG

Switzerland · AI-generated

business travel switzerland

ONLINE-TRAVEL is the autonomous system for Online Travel AG.

What it's used for

  • The address space carries the corporate network for Online Travel AG, evidenced by the netname ONLINE-TRAVEL and registrant Online Travel AG for the sole prefix.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (193.135.59.0/24) and maintains 2 observed neighbours, a ratio consistent with a small business or internal corporate estate rather than a transit or access provider.

Notable

  • The registrant Online Travel AG matches the AS handle and the announced prefix, indicating direct ownership of the address space.
  • Online Travel AG was part of the MyTravel Group, which merged with Thomas Cook AG in 2007 to form Thomas Cook Group plc; the group entered compulsory liquidation in 2019.
  • The inventory consists of a single contiguous /24 block in Switzerland, with no IPv6 prefixes announced.

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: 446 networks and 1,852 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.
