Unclassified APNIC
Summary
Sonangol
business government energy corporate
SONANGOL is operated by Sonangol, the Angolan state-owned petroleum company.
What it's used for
- The address space carries corporate infrastructure, evidenced by the reverse DNS record
teste.snl-sonip.co.aopointing to a Sonangol subsidiary domain. - The AS announces 1024 IPv4 addresses within a single prefix (41.223.164.0/22) and maintains 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
Notable
- The RDAP registrant
Sonangoland netnameORG-SA61-AFRINICalign directly with the AS holder, confirming consistent ownership of the address space. - Sonangol is a parastatal entity formerly overseeing petroleum and natural gas production in Angola, established in 1976.
- The inventory consists of a single /22 block with no IPv6 prefixes, reflecting a minimal and focused address allocation for internal corporate use.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,771 prefixes, as published 2026-10-15. 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.
