You would think it would be easy to find this information, but none of the Github or Gandi documentation is clear so I have recorded the required steps here.
Create the following A records:
@ 1800 IN A 185.199.108.153
@ 1800 IN A 185.199.109.153
@ 1800 IN A 185.199.110.153
@ 1800 IN A 185.199.111.153
Remove the Gandi parking page A record:
@ 10800 IN A 217.70.184.38
Create the following CNAME record:
www 10800 IN CNAME [github-username].github.io.
Remove the Gandi parking page CNAME record:
www 1800 IN CNAME webredir.vip.gandi.net.
Finally, in your Github repo create a file called CNAME
which contains your Gandi domain name, e.g. [my-domain].io
.
GitHub Pages IP addresses are also available here: https://help.github.com/en/github/working-with-github-pages/managing-a-custom-domain-for-your-github-pages-site
