What it's used for
- The address space carries data center and business infrastructure, evidenced by netnames such as
DATAFOUNDRY,YHC-4, andYHC-3. - Reverse DNS entries follow the pattern
cust-<ip>.switchnap.com, indicating customer allocations within the Switch network. - The AS announces 311,552 IPv4 addresses across 253 prefixes and 65 IPv6 prefixes, with 143 observed neighbours, suggesting a role focused on hosting and interconnection rather than pure transit.
Notable
- All registrants in the evidence pack are listed as
SWITCH, LTD, consistent with the announcer. - The address inventory is diverse, including blocks previously associated with other entities like
INSYNC4andDATAFOUNDRY, reflecting acquisitions or historical allocations now managed by Switch. - The network is finely subdivided with many /19 and /20 prefixes, typical of a large-scale data center operator managing distinct customer or service segments.

Internet exchanges
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 2026-10-16, 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 2026-10-17. 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.
