About this ASN.

Updated  ·  Confidence: High

AS21928 is T-Mobile USA's autonomous system, registered under ARIN, with the IRR as-name "TMobileUSA" and the description "T-Mobile USA IP Backbone." It carries the company's US cellular handset traffic and, increasingly, its fixed-wireless and fiber consumer products — T-Mobile Home Internet and T-Mobile Fiber. The network holds roughly 12–13 million IPv4 addresses (prefix counts vary widely across aggregators) plus a sizable IPv6 footprint, and historically takes transit from carriers including Level 3/Lumen (AS3356), AS3549, and AS6461. After the 2020 Sprint merger, Sprint's legacy ASNs — notably AS1239 and AS6296 — folded into the T-Mobile family, so analysts may still see those numbers in historical paths. The central triage caveat is carrier-grade NAT on the mobile side: a single public IP routinely represents many subscribers and is dynamically reassigned, defeating point-in-time IP-to-user attribution. T-Mobile Home Internet and T-Mobile Fiber also sit behind CGNAT, which compounds the shared-IP ambiguity for what looks like fixed-line traffic. Sprint Corporation and T-Mobile US completed their all-shares merger on April 1, 2020, with T-Mobile as the surviving brand.

Security/abuse context

CGNAT mobile network — one IP commonly maps to many subscribers and is dynamically reassigned; Home Internet/Fiber also use CGNAT, compounding shared-IP ambiguity. Third-party mobile/bittorrent/crawler tags reflect a large consumer pool. No notable distinct public abuse-dataset ranking found as of 2026-06-06 — ipinfo.io

Network & routing

Our research recorded 924 IPv4 prefixes; RIPEstat currently announces 269.
Network type
mobile-carrier [Confirmed] — operator + IRR (RADB "T-Mobile USA IP Backbone")
Size
~491–1,848 IPv4 prefixes (sources disagree; ~12.2M–13.1M addrs), ~410 IPv6 — bigdatacloud.com / ipqualityscore.com / bgp.he.net (2026-05/06)
Routing/peering
largely a leaf eyeball network (~11–12 IPv4 peers); historical upstreams AS3356, AS3549, AS6461 (RADB); PeeringDB record exists (net/3592) but sparse; RPKI unknown — bgp.he.net, ipinfo.io
Notable usage
T-Mobile USA's mobile/IP backbone; also carries T-Mobile Home Internet (FWA) and T-Mobile Fiber (FTTH) — t-mobile.com
Related ASNs
AS1239 (Sprint, legacy), AS6296 (Sprint PCS, legacy), plus other T-Mobile ASNs
Analyst note
Encountered as US mobile subscriber traffic; CGNAT means a single IP maps to many subscribers and is dynamically reassigned, so avoid per-IP attribution. Home Internet/Fiber are also CGNAT.
