Summary
Cloudsmart (RECOL)
hosting isp legacy
RECOL-CT is Cloudsmart, a Branford, Connecticut managed service and datacentre operator. The company started in 1995 as RECOL, a business-focused ISP, and rebranded to Cloudsmart around 2016 — which is why the AS handle, the legacy netnames and the reverse DNS still say recol.
What it's used for
RIS shows 6 announced IPv4 prefixes, 4,864 addresses, 1 IPv6 prefix (2606:7800::/32) and 6 observed neighbours. Five of the six IPv4 prefixes are contiguous blocks out of 64.207.96.0, all registered to Cloudsmart under RECOL-LLC; the sixth, 199.21.248.0/22, registers to Cloudsmart as well under ISG-NETBLK001. Every prefix is first-party. There are no unrelated third-party registrants, so the leasing shape does not apply.
The reverse DNS is the interesting part because it shows two eras of the business coexisting in one AS. 64-207-100-133.dsl.ct.recol.net is a DSL subscriber name from the ISP era — templated, per-address, in the dsl.ct.recol.net zone. mx1.easternfiredoor.com on the same /24 is a customer's mail server, an individually named business host of the sort a colocation or managed-hosting provider runs. unassigned.isgsoftware.net across the 199.21.248.0/22 marks space held but not currently allocated.
Notable
Six neighbours against under 5,000 addresses is a regional provider with several upstreams, not a carrier. The primary business today is datacentre, colocation, cloud and backup for MSPs and municipalities, so hosting is the honest classification — with the caveat, visible right there in the PTRs, that legacy business-DSL access lines still live in the same space.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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 1,784 prefixes, as published 2026-10-19. 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.
