People with admin permissions for a repository can configure a custom domain for a {% data variables.product.prodname_pages %} site.
|
|
|
|
### About custom domain configuration
|
|
|
|
Make sure you add your custom domain to your {% data variables.product.prodname_pages %} site before configuring your custom domain with your DNS provider. Configuring your custom domain with your DNS provider without adding your custom domain to {% data variables.product.product_name %} could result in someone else being able to host a site on one of your subdomains.
|
|
|
|
{% windows %}
|
|
|
|
The `dig` command, which can be used to verify correct configuration of DNS records, is not included in Windows. Before you can verify that your DNS records are configured correctly, you must install [BIND](https://www.isc.org/bind/).
|
|
|
|
{% endwindows %}
|
|
|
|
{% note %}
|
|
|
|
**Note:** DNS changes can take up to 24 hours to propagate.
|
|
|
|
{% endnote %}
|
|
|
|
### Configuring a subdomain
|
|
|
|
To set up a `www` or custom subdomain, such as `www.example.com` or `blog.example.com`, you must create a _CNAME_ file in your site's repository and configure a `CNAME` record with your DNS provider.
|
|
|
|
{% data reusables.pages.navigate-site-repo %}
|
|
{% data reusables.repositories.sidebar-settings %}
|
|
{% data reusables.pages.save-custom-domain %}
|
|
5. Navigate to your DNS provider and create a `CNAME` record that points your subdomain to the default domain for your site. For example, if you want to use the subdomain `www.example.com` for your user site, create a `CNAME` record that points `www.example.com` to `<user>.github.io`. If you want to use the subdomain `www.anotherexample.com` for your organization site, create a `CNAME` record that points `www.anotherexample.com` to `<organization>.github.io`. The `CNAME` file should always point to `<user>.github.io` or `<organization>.github.io`, excluding the repository name. {% data reusables.pages.contact-dns-provider %}{% data reusables.pages.default-domain-information %}
|
|
{% data reusables.command_line.open_the_multi_os_terminal %}
|
|
6. To confirm that your DNS record configured correctly, use the `dig` command, replacing _WWW.EXAMPLE.COM_ with your subdomain.
|
|
```shell
|
|
$ dig <em>WWW.EXAMPLE.COM</em> +nostats +nocomments +nocmd
|
|
> ;<em>WWW.EXAMPLE.COM.</em> IN A
|
|
> <em>WWW.EXAMPLE.COM.</em> 3592 IN CNAME <em>YOUR-USERNAME</em>.github.io.
|
|
> <em>YOUR-USERNAME</em>.github.io. 43192 IN CNAME <em> GITHUB-PAGES-SERVER </em>.
|
|
> <em> GITHUB-PAGES-SERVER </em>. 22 IN A 192.0.2.1
|
|
```
|
|
{% data reusables.pages.build-locally-download-cname %}
|
|
{% data reusables.pages.enforce-https-custom-domain %}
|
|
|
|
### Configuring an apex domain
|
|
|
|
To set up an apex domain, such as `example.com`, you must configure a _CNAME_ file in your {% data variables.product.prodname_pages %} repository and an `ALIAS`, `ANAME`, or `A` record with your DNS provider.
|
|
|
|
{% data reusables.pages.www-and-apex-domain-recommendation %}
|
|
|
|
{% data reusables.pages.navigate-site-repo %}
|
|
{% data reusables.repositories.sidebar-settings %}
|
|
{% data reusables.pages.save-custom-domain %}
|
|
5. Navigate to your DNS provider and create either an `ALIAS`, `ANAME`, or `A` record. {% data reusables.pages.contact-dns-provider %}
|
|
- To create an `ALIAS` or `ANAME` record, point your apex domain to the default domain for your site. {% data reusables.pages.default-domain-information %}
|
|
- To create an `A` record, point your apex domain to the IP addresses for {% data variables.product.prodname_pages %}.
|
|
```shell
|
|
185.199.108.153
|
|
185.199.109.153
|
|
185.199.110.153
|
|
185.199.111.153
|
|
```
|
|
{% data reusables.command_line.open_the_multi_os_terminal %}
|
|
6. To confirm that your DNS record configured correctly, use the `dig` command, replacing _EXAMPLE.COM_ with your apex domain. Confirm that the results match the IP addresses for {% data variables.product.prodname_pages %} above.
|
|
```shell
|
|
$ dig <em>EXAMPLE.COM</em> +noall +answer
|
|
> <em>EXAMPLE.COM</em> 3600 IN A 185.199.108.153
|
|
> <em>EXAMPLE.COM</em> 3600 IN A 185.199.109.153
|
|
> <em>EXAMPLE.COM</em> 3600 IN A 185.199.110.153
|
|
> <em>EXAMPLE.COM</em> 3600 IN A 185.199.111.153
|
|
```
|
|

|
|
{% data reusables.pages.enforce-https-custom-domain %}
