FAQ: add standby allowlist IPs, drop rows that have no static IP - #456
Merged
Merged
Conversation
Every published endpoint (.lc, .edr, .wss, .ingest in each region) now has a second, standby IP reserved for it. Customers should allow both so future infrastructure changes on our side never require another allow-list update. The standby addresses are not serving yet; they enter service after 2026-10-28. Also removes rows that were never correct: the Replay/Webhook entries for the non-Australia regions listed a Google front-end address rather than a LimaCharlie IP (those hostnames have no static IP), and the Live feed rows described an endpoint no client uses.

Why
Every published allow-list endpoint (
.lc,.edr,.wss,.ingestin each of the six regions) now has a second static IP reserved for it (refractionPOINT/tracking#4710). Customers allow both addresses; later infrastructure changes on our side then never require another allow-list update.The standby addresses are not serving yet — they're reserved and dark until after the customer adoption window (activation planned 2026-10-28). The page says so.
Changes to
docs/8-reference/faq/sensor-installation.md.lc,.edr,.wss,.ingest(24 pairs). Australia's Replay/Webhooks rows keep their single IP (—in the new column).142.250.115.121— a Google front-end address, not a LimaCharlie IP (those hostnames are Cloud Run domain mappings with no static IP)..live) in all regions — no client uses it (verified from load-balancer logs).Source of truth for the addresses:
