# ri-edge-dns
Public edge DNS notes (Drew Halvorsen).
This is scratch for the anycast edge, not the full runbook. The pulse *parser*
lives in a different tree — I am not duplicating it here after last quarter's
drift page.
## Pulse location
Edge DNS pulse is **TXT `_risk.ops`**.
If you need the record body / hostname template, ask on-call or read the
runbooks repo. This file only says **where** to look.
## Abuse / blocks
`203.0.113.50` is blocked after a brute-force against the contractor portal
and the git front-door. Do not lift that without Priya Nandakumar on the CAB.
## Windows resolvers
If you are changing records that CORP still caches, mail userX@corp.local
before the Friday window — he owns the Windows DNS side.
