Autonomous system
AS6688 ATT-GCH-VOI-LA-AS VoIP platform - ex Concert
Unclassified RIPE
Summary
AT&T Global Network Services (VoIP platform, Los Angeles)
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
/24of 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.
