Summary
Angola Telecom
isp transit legacy
AS11259 is Angola Telecom, the state-owned incumbent telecommunications operator of Angola, headquartered in Luanda. It is one of the country's principal carriers of fixed-line and internet service, and the AS is its main routed network.
What it's used for
RIS observes 71 IPv4 prefixes carrying roughly 140,288 addresses, one IPv6 prefix (2c0f:faf0::/32), and 14 observed neighbours. That is the profile of a national incumbent rather than an enterprise: a large, mostly contiguous address estate carrying subscriber and business access, with enough BGP adjacencies to reach international transit and regional peers without being a global wholesale carrier itself.
The address estate is dominated by AFRINIC space around 197.216.0.0/15 and 197.217.0.0/17, deaggregated into a long tail of /22s and /23s. That deaggregation pattern is how an access network slices allocations across regions, POPs and product lines. Two older blocks sit outside it: 41.74.240.0/20, registered to ORG-AT1-AFRINIC (Angola Telecom), and 66.110.112.0/20, an ARIN block registered as ANGOLATELECOM-TGB — legacy space acquired before AFRINIC's African allocations were the default.
Notable
The prefix registrant lookup is the part that needs reading carefully. Several of the 197.216/197.217 blocks come back with an org that is an individual's name rather than a company. That is an AFRINIC record-keeping pattern, where the RDAP entity surfaced for an inetnum is its named contact person, not a separate corporate holder. It is not the signature of IP leasing, which requires several unrelated companies registering space across multiple RIRs at once. The covering allocations are Angola Telecom's own.
Interesting
IPv6 is present but minimal: a single /32 against 71 IPv4 routes. The v6 block is allocated and announced, so the network is reachable over IPv6, but the imbalance suggests deployment has not gone much beyond the routing table.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
