Summary
Internap / Unitas Global
hosting enterprise legacy
INTERNAP-BLK is one of the address-holding autonomous systems of Internap (INAP), the Atlanta-founded managed hosting and "route-optimized" IP transit provider, now held by Unitas Global after Unitas acquired INAP's network and connectivity business out of its restructuring.
What it's used for
RIS sees 40 IPv4 prefixes / 44,032 addresses plus a single IPv6 prefix (2600:c04::/32) originated here, against just 6 observed neighbours. That combination is the signature of a hosting and colocation footprint rather than a wholesale carrier: a transit business of Internap's former stature would show hundreds of BGP adjacencies, not six. The prefixes are a scatter of legacy /20–/24 blocks across 63.251/16, 64.74/16, 66.150/16, 66.151/16, 74.201/16, 74.217/16 and 216.52/16 — the accumulated customer-assignment space of a company that grew by acquisition through the 2000s.
Notable
The sampled reverse DNS lands on a customer, not the operator: 64.74.168.5 resolves to 5-168-74-64.nonfatmedia.com. That is exactly what colocation and dedicated-server space looks like, where the tenant owns the PTR. It is also a reminder that rDNS tells you what a block carries, never who holds it.
Interesting
The -BLK suffix in the handle is the giveaway that this ASN's job is to hold and announce address space, not to be the company's transit identity. Internap ran several ASNs in parallel; the fragmentation of the prefix list here — dozens of small blocks, no large aggregate — is the fossil record of many small allocations rather than one big one.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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 1,783 prefixes, as published 2026-10-20. 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.
