Summary

Sony Interactive Entertainment

Japan · AI-generated

business gaming corporate

SCEI-NET is operated by Sony Interactive Entertainment.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname SCEI-NET and registrant Sony Interactive Entertainment LLC administrator.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix with only 1 observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate endpoints, development infrastructure, and backend services for Sony's video game and digital entertainment platforms.

Notable

  • The registrant Sony Interactive Entertainment LLC administrator aligns with the AS handle SCEI-NET, reflecting the company's rebranding from Sony Computer Entertainment Inc.
  • Sony Interactive Entertainment LLC was formed from the merger of Sony Computer Entertainment Inc. and Sony Network Entertainment, explaining the retention of the SCEI handle.
  • The inventory consists of a single /24 IPv4 block and a /48 IPv6 prefix, representing a minimal footprint for a major global technology company.

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.
