AS3549 — LVLT-3549

Network type: transit

AS3549 announces 3,168 IPv4 prefixes covering 4,520,960 addresses and 138 IPv6 prefixes.

About this network

A major global backbone (LVLT-3549) now operated by Lumen — the former Global Crossing network, which Level 3 acquired before merging into Lumen.

What it's used for

• Global IP transit and wholesale backbone connectivity, especially on long-haul and submarine routes Global Crossing originally built.

Notable

• Sits alongside AS3356 (the Level 3 core) inside Lumen; 3549 is the absorbed Global Crossing footprint, still announced under its own ASN.
• A Tier 1-class backbone reaching the whole internet via peering.

Interesting

• Global Crossing famously laid a global submarine-cable network in the late 1990s; that fibre lives on inside Lumen today.
