Summary

Meta Platforms

United States of America · AI-generated

business corporate infrastructure

FACEBOOK-CORP is operated by Meta Platforms.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames Facebook-Corp and FACEBOOK-CORP and registrants including Meta Platforms Ireland Limited and Facebook Inc.
  • The AS announces 5120 IPv4 addresses across 2 prefixes and 8 IPv6 prefixes, with only 3 observed neighbours, indicating a small, internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate endpoints, data center services, and engineering infrastructure supporting Meta's global platform operations.

Notable

  • Registrants align with the announcer, listing Meta Platforms Ireland Limited for the 163.114.128.0/20 block and Facebook Inc for the 199.201.64.0/22 block.
  • The operator was formerly known as Facebook, Inc., rebranding to Meta Platforms, Inc. in 2021 to reflect a strategic shift toward the metaverse and broader technology initiatives.
  • The inventory consists of two distinct IPv4 blocks and a contiguous range of IPv6 prefixes, reflecting a segmented internal network design.

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.
