Summary
Infinity Broadband
isp hosting business
Half the blocks belong to somebody else, and three of them are named after a registry on another continent.
What it's used for
- A broadband provider's network. Nine prefixes announced from the Cayman Islands, one of them IPv6, six thousand nine hundred and twelve addresses, through one observed BGP neighbour.
Notable
- Three blocks are registered to an address holding company and share a netname that is not a name at all: the letters for an organisation, four characters of identifier, and then the name of a regional registry from another continent. It is a database key that leaked into the network's public record.
- Three more blocks carry the provider's own name in full, matching the AS handle word for word.
- One block shortens that to three initials and a two-digit numeral. One belongs to a transcoding company and is named after its initials.
- So the eight registered blocks span four owners' naming habits and three separate owners.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Address space that carries another registry's organisation handle has usually been leased rather than allocated. The record shows where the addresses came from, not where they are used, and the two are an ocean apart.
- One upstream for a provider on an island is the whole path off it. Everything here depends on a single neighbour agreeing to keep carrying it.
- A network built from four owners' blocks is a working network held together by contracts. Nothing in the registry connects the parts; only the routing does.

Reputation
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 1,773 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.
