About this network

BTN-TWO — originally Beyond The Network America, Inc. (BTN), a US network operator that became part of PCCW Global. The ASN is now registered to PCCW Global (HK) Ltd. and appears in APNIC's registry after an inter-RIR transfer.

What it's used for

• Carries PCCW Global network space, including the legacy BTN 65.72.0.0/16 block that moved to APNIC with the ASN, and European prefixes registered to PCCW Global Europe — one of which is named for a mobility/IoT platform in Ashburn, Virginia.
• Announces both IPv4 and IPv6, but a modest footprint compared with PCCW Global's main backbone AS.

Notable

• A carrier network rather than an eyeball or hosting one: the address space supports PCCW Global's own platforms and downstreams, and the historic AS-BTN-CUSTOMERS object still records the BTN customer cone.
• A neat example of an ASN outliving two corporate identities and crossing RIRs along the way.
