Summary
NEC Corporation
business corporate japan infrastructure
NEC is operated by NEC Corporation.
What it's used for
- The address space carries corporate infrastructure, evidenced by the netname
NEC-CIDR-BLK-JPassociated with both announced IPv4 prefixes. - The AS announces 6144 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
Notable
- Registrants for the largest prefixes are listed as Japan Network Information Center, which is consistent with the holder being a major Japanese corporation.
- The address inventory consists of two distinct IPv4 blocks,
203.179.16.0/20and121.100.8.0/21, alongside a single IPv6 prefix,2401:2680::/32.

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.
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.
