AS32934

AS32934 is Meta's primary autonomous system, registered to Facebook, Inc. (now Meta Platforms) under ARIN and active since August 2004. It originates and edges the address space behind Facebook, Instagram, WhatsApp, and Messenger, as well as Meta's edge caches — the Facebook Network Appliance (FNA) nodes that operators host inside their own networks. Related networks in the AS-FACEBOOK set include AS32934 itself plus AS54115, AS34825, AS63293 (off-net edge caches), and AS11917, alongside AS-FACEBOOK-CORP. Like other large content providers, AS32934 announces more IPv6 than IPv4 prefixes, and its RPKI coverage is clean (originated prefixes valid, none invalid in the observed view). The key difference from multi-tenant cloud ASNs is low ambiguity: this space is almost entirely first-party Meta services, not customer workloads, so an address here is either Meta traffic or an FNA cache embedded in an ISP — it is rarely, if ever, a third-party tenant network. That makes attribution from an AS32934 IP relatively straightforward compared with AWS, Azure, or GCP.

Operator

Facebook, Inc. / Meta Platforms (ARIN OrgId THEFA-3) [Confirmed] — ARIN RDAP/WHOIS

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP

Security/abuse context

no notable public abuse signal against Meta's own ASNs as of 2026-06-03; shared-IP ambiguity is minimal because the space is almost entirely first-party (not multi-tenant cloud) — bgp.he.net

Analyst note

An IP here is Meta first-party traffic or an FNA cache inside an ISP. Low ambiguity — rarely a customer/tenant network.
