We check a request's IP address for blocks owned by GitHub as a form of authentication for service hooks to consume commits and implement continuous integration/delivery on a project.

They list these blocks in the service hooks configuration page. Are these address blocks also due for change/deprecation?

Better to ask the source, I'd say. Per the bar at the bottom of the GitHub post:

    Have feedback? Let @github[1] know on Twitter.

Yes, the 204.232.175.* IPs went away, 192.30.252.0/22 are still here.
