AS13414

AS13414 is the global content autonomous system number registered under ARIN to Twitter Inc., the operator of the social platform now branded X. The ARIN org record (handle TWITT) still carries the legal name "Twitter Inc." at 1355 Market Street, San Francisco, but operationally the network belongs to X Corp.: Twitter Inc. merged into X Corp. in April 2023, and X Corp. became a wholly owned subsidiary of xAI on 2025-03-28. PeeringDB classifies the network as Content with a Heavy-Outbound traffic ratio and a Selective peering policy (100 Mbit/s minimum, interconnection at the nearest POP to the home market, no ratio or contract requirement). Routing is healthy and globally visible: RIPEstat shows 39 active IPv4 prefixes (~41,984 addresses) and 3 IPv6 prefixes, with 326/326 RIS peers seeing the IPv4 routes and near-full IPv6 visibility, spanning ARIN (US), RIPE (EU/Amsterdam) and APNIC (APAC/Japan-Singapore) blocks via anycast. The security record shows AS13414 as a victim, not a source: it was the target of two censorship-motivated BGP prefix mis-originations of 104.244.42.0/24 — by AS136168 (Myanmar) in February 2021 and by RTComm AS8342 (Russia) in March 2022 — after which the operator deployed RPKI ROAs that demonstrably limited the second event's spread. No notable abuse signal was found across Spamhaus, AbuseIPDB (0% confidence on sampled IPs), CleanTalk (low, noisy outbound-mail rates), or NANOG archives as of June 2026.

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum/13414

Allocated

2010-07-09 (ARIN RDAP autnum TOP-LEVEL registration event; RIR registry date, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 2015-02-19 [Confirmed by two angles A2+A3] — rdap.arin.net/registry/autnum/13414

Org status

active. X Corp. is a privately held Nevada corporation (incorporated 2023-03-09); Twitter Inc. (Delaware) merged into it in April 2023; wholly owned by xAI since 2025-03-28. ARIN status: ok [Confirmed] — ARIN RDAP, en.wikipedia.org/wiki/X_Corp.

Security/abuse context (NEUTRAL, DATED)

victim (not source) of two BGP prefix mis-originations of 104.244.42.0/24 — AS136168 (Myanmar, Feb 2021) and RTComm AS8342 (Russia, 28 Mar 2022), both censorship-motivated. No notable abuse signal as of 2026-06: AbuseIPDB 0% confidence on sampled IPs, CleanTalk low/noisy rates, no Spamhaus ASN listing; a 2010 Spamhaus SBL listing (SBL84807) was transient and email-invitation-related, not IP-infrastructure

Network & routing

Network type

Content — global anycast content network, Heavy-Outbound traffic ratio, IPv4 + IPv6 unicast [Confirmed] — peeringdb.com/asn/13414

Size

39 active IPv4 prefixes (~41,984 addresses) and 3 IPv6 prefixes; 32 observed BGP neighbours [Confirmed] — RIPEstat routing-status (2026-06-25). bgp.he.net reports 41 IPv4 / 4 IPv6 originated prefixes and ~42,240 IPs (third-party count) [Likely] — bgp.he.net/AS13414

Routing/peering

announced and fully visible — 326/326 RIS peers see the IPv4 routes, 322/323 see IPv6; first seen in routing 2000-08-18 (prefix 216.174.0.0/21). Selective peering policy: 100 Mbit/s minimum, interconnect at nearest POP, multiple locations preferred, no ratio, no contract

[Confirmed] — RIPEstat routing-status, peeringdb.com/asn/13414

RPKI

ROAs deployed following the 2021 Myanmar hijack attempt; they limited the March 2022 RTComm mis-origination. Per-prefix validation not run in this pass (CAIDA timed out; no single prefix supplied) — posture is Likely partial-to-good

[Likely] — manrs.org/2022/03/lesson-learned-twitter-shored-up-its-routing-security

Upstreams / transit

SpaceX (AS14593), Arelion (AS1299), NTT America (AS2914), Hurricane Electric (AS6939) per bgp.he.net [Likely — single-source, CAIDA upstream split was Unknown] — bgp.he.net/AS13414

IX presence

18+ IXPs including AMS-IX, DE-CIX Frankfurt, DE-CIX ASEAN, BBIX Osaka, and multiple Equinix locations (10G–100G) [Likely — third-party] — bgp.he.net/AS13414, peeringdb.com/asn/13414

Notable usage

operates the X (formerly Twitter) platform, with Grok AI integration via xAI; previously ran Periscope and MoPub (both defunct). Anycast used for global delivery [Confirmed] — peeringdb.com/asn/13414, en.wikipedia.org/wiki/X_Corp.

Analyst note

ARIN org name lags the corporate reality (still "Twitter Inc."). The autnum TOP-LEVEL registration (2010-07-09) is the allocation date — not the org-entity TWITT "last changed" 2026-06-24, which is a record update. Clean, well-routed content ASN with a proactive routing-security posture.
