Summary

AT&T Global Network Services (VoIP platform, Los Angeles)

United States · AI-generated

enterprise legacy

ATT-GCH-VOI-LA-AS is the Los Angeles half of a pair of small AT&T Global

Network Services autonomous systems carrying a VoIP platform. The registrant

is AT&T Global Network Services Nederland B.V., the Dutch entity holding this

legacy RIPE space.

What it's used for

  • A single /24 of infrastructure address space for a voice-over-IP platform, not subscriber or customer addressing.
  • The San Francisco counterpart is [AS6686](https://asn.ipinfo.app/AS6686), on the adjacent /24.

Notable

  • RIPE records the platform as ex-Concert — the AT&T/BT global joint venture launched in 1998 and dissolved in 2002, whose network assets were split back to the two parents. The handle preserves that lineage decades later.
  • A carrier service-platform AS: small, static, and not an eyeball or transit network.

Interesting

  • Two consecutive-ish AS numbers, two coasts, two adjacent /24s — an east/west redundancy pair visible entirely from registry and routing data.
