GitHub Pages Custom Domain Settings

Question

3.3k views Asked by Gurinder At 14 June 2015 at 18:36

I'm trying to configure GitHub with my naked domain.com (APEX in GitHub) and www.domain.com.

I have username.github.io working OK.

My A record is pointing to 192.30.252.153 and 192.30.252.154.

I then have two CNAME records set:

This configuration, however, is not working.

Accessing domain.com results in a 404 on GitHub. Meanwhile, accessing www.domain.com results in an ERR_NAME_NOT_RESOLVED.

Existing documentation is confusing and there's no clear way of configuring things end-to-end.

Can someone tell me what I'm missing?

Based on Erik's answer, here's the slightly modified configuration that worked for me.

For my custom (apex) domain eyecatchup.rocks, I set:

With this set, both eyecatchup.rocks as well as www.eyecatchup.rocks point to my GitHub user page, originally available at eyecatchup.github.io.

The following configuration at your DNS provider side is needed:

Here's what I've done to get domain.com and www.domain.com working you'll need this:

An A record for www
An A record @ 192.30.252.153
An A record @ 192.30.252.154
A CNAME aliasing www.domain.com to username.github.io. (note the trailing period)
The "CNAME" file in the GitHub Pages repo contains the text "domain.com"

I think the wildcard A record may be optional in your case but I'm not certain.

Edit: Removed wildcard A record. @mheadroom pointed out that GitHub recommends against this entry because it would allow anyone to host a GitHub Pages site on one of your subdomains! https://help.github.com/articles/tips-for-configuring-a-cname-record-with-your-dns-provider/
