Fix recdns config on various hardware devices
Open, MediumPublic


There are two legacy recdns IPs which are still supported (for now) and still in active use by a few devices: and These should both be replaced in all config with with instead. Most of the migration was done months ago, but some hardware devices remain on the old config. A recent 24h packet capture survey turned up several clients:

  • ps1-[abcd][1-8]-codfw (All 32x PDUs in codfw)
  • ps1-[cd][1-8]-eqiad (All 16x PDUs in eqiad rows C and D)
  • ps1-b5-eqiad
  • asw-c-eqiad
  • ps1-22-ulsfo
  • pfw3-eqiad
  • pfw3-codfw

It might be worth auditing all of the PDU configs, in case some of them simply didn't show up in queries during the 24h window, given how many of them did so.
