What it's used for
- The address space is registered under netnames
PCC-CORP-1andPCC-CORP-2, indicating a dedicated corporate network rather than a service provider or hosting facility. - The AS announces 3,584 IPv4 addresses across 4 prefixes with 7 observed neighbours, a ratio consistent with an internal corporate estate segmented by site or function rather than a transit or access network.
- Traffic from this AS consists of office workers, engineering staff, and industrial control systems across the company's global manufacturing operations.
Notable
- All registrants in the RDAP data match the announcer, listing
PRECISION CASTPARTS CORPfor every prefix. - The address inventory is composed of four distinct IPv4 blocks, including a /21, a /22, and two /24s, all located in the United States.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
7 upstream, 0 downstream and 7 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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 1,773 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.
