Summary

United States of America · AI-generated

security business cloud legacy

The AS handle SECURITYSERVICES is held by Arbor Cloud.

What it's used for

  • The address space carries a mix of corporate and third-party allocations, with netnames including NS-807 for Arbor Cloud, KW-NBK-20061109 for National Bank of Kuwait, and SAMA for Saudi Central Bank.
  • The AS announces 33536 IPv4 addresses across 79 prefixes and 14 IPv6 prefixes, while maintaining 45 observed neighbours, a ratio consistent with a business or security service provider rather than a large access network.

Notable

  • Registrants in the RDAP data include Arbor Cloud, National Bank of Kuwait S.A.K.P, Saudi Central Bank (SAMA), and Cyberia Ripe Administration, indicating the AS aggregates space from multiple distinct entities.
  • The operator was formerly known as Neustar Security Services, which was acquired by Arbor Networks and rebranded as Arbor Cloud.
  • The inventory includes a significant block of 156.154.0.0/16 space alongside numerous /23 prefixes from various global regions.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
