Summary
Coolwave Communications
enterprise telecom legacy
CARRIER1-AS is held today by Coolwave Communications Limited, a Dublin wholesale voice and messaging carrier (SIP trunking, voice origination and termination, global DIDs, A2P SMS, IoT SIMs). Coolwave is now part of the Gamma group — Gamma Telecom appears as one of the AS's upstreams.
What it's used for
- Carrier infrastructure for Coolwave's voice and messaging platform, not consumer or hosting services: roughly 24,000 IPv4 addresses across
212.4.192.0/19and213.239.0.0/18, with no IPv6 announced. - The AS peers heavily for its size, including at AMS-IX and NL-ix — what a voice/messaging wholesaler needs in order to reach its interconnect partners cheaply.
Notable
- The
CARRIER1name is a handle that outlived its holder. Inside212.4.192.0/19the individual /24s are stillCARRIER1-NETSobjects under aCARRIER1-MNTmaintainer, while the enclosing allocations were renamed toIE-COOLWAVE-19980810andIE-COOLWAVE-20000228. Nothing about the current network is a 1990s pan-European carrier. - Essentially no rDNS resolves across either block, and the delegated reverse servers for the
212.4space do not answer — so there is no eyeball, hosting or subscriber signature to be found. The space backs a B2B telecoms platform.
Interesting
- The
aut-numobject still carries import policies for a long list of customer ASNs that no longer appear in the routing table. Routing-policy objects age badly, and a staleaut-numcan make a network look far larger than it is.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
