Summary
Telecom Cook Islands (Vodafone Cook Islands)
CKTELECOM-CK-AP is Telecom Cook Islands, trading as Vodafone Cook Islands — the incumbent and effectively sole telecommunications operator of the Cook Islands, founded in 1991 and now owned by Amalgamated Telecom Holdings. AS10131 is the national eyeball network.
What it's used for
Fixed broadband, mobile and fixed-line service for households and businesses across Rarotonga and the outer islands. The AS announces 18 IPv4 prefixes totalling roughly 8,192 addresses (a 202.65.32.0/19 with its /21s and /24s deaggregated for traffic engineering) and no IPv6. The sampled reverse DNS is subscriber naming throughout: hosts like 202-65-56-5.xdsl.net.oyster.net.ck sit under the operator's own oyster.net.ck service domain, with xdsl marking the DSL access concentrators the customers hang off. The exception is telling in its own way — r0-akl.net.oyster.net.ck is a router in Auckland, which is where the islands' transit actually lands.
Notable
This is an eyeball network. Roughly 8,000 addresses against only 12 observed BGP neighbours is the access-ISP silhouette: a wholesale carrier of comparable size would peer with hundreds of ASes, while an island incumbent buys transit from a couple of New Zealand upstreams. Geolocate this space to Cook Islands end users, not to a data centre.
Interesting
Almost an entire country's internet population sits behind a single /19. The oyster.net.ck domain long predates the Vodafone branding, so the network's own naming still reflects the original Telecom Cook Islands identity.

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 1,783 prefixes, as published 2026-10-17. 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.
