Summary

CityBook Services Ltd

Israel · AI-generated

business outsourcing israel

CITYBOOK-SERVICES-LTD is operated by CityBook Services Ltd.

What it's used for

  • The address space carries a single /24 block with the netname Citybook-Services-Ltd and registrant Citybook Services Ltd.
  • The AS announces 256 IPv4 addresses across 1 prefix and maintains 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate infrastructure for an outsourcing firm providing back-office services, including sales and medical billing, to international clients.

Notable

  • The RDAP registrant Citybook Services Ltd matches the AS handle and the announced prefix netname.
  • The address inventory is minimal, consisting of a single contiguous /24 block, which fits the profile of a private corporate estate.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
