How long does it take for GitHub to allocate domain names?

GitHub Pages is a free static website hosting service provided by GitHub. Users can add a "special branch" dedicated to storing static pages in their own GitHub repository. GitHub is responsible for parsing the content on this branch and passing it through Access is provided by the HTTPS protocol.

In order to facilitate users to deploy personalized websites on GitHub Pages, GitHub also provides the function of customizing domain names, allowing users to bind domain names they already own to sites hosted by GitHub Pages. At this time, GitHub will automatically assign a DNS record to the user. The user only needs to add the DNS record to his domain name configuration in his domain name management background, and he will be able to access the site through his own domain name.

So, how long does it take for GitHub to allocate domain names? Let’s take a closer look below.

Step one: Add your own domain name to GitHub Pages

Before using your own domain name to access GitHub Pages, we need to add your own domain name to GitHub Pages. The process is very simple and only requires some basic configuration to complete. The specific steps are as follows:

1. Open the settings page of the GitHub warehouse and find the "GitHub Pages" option;
2. Enter your domain name in the "Custom domain" column and click "Save" " button;
3. GitHub will automatically generate a DNS record for you (such as the IP address of "xxx.github.io") so that you can configure it into your domain name background.

Step 2: Add DNS records to the domain name configuration

After completing the above steps, we need to add the generated DNS records to the configuration file of our own domain name.

Add a CNAME record in the management background of the domain name, set the name field of the record to "WWW", and set the value field of the record to the DNS record we generated in the first step.

Since the propagation of DNS records takes a certain amount of time, you need to wait for a certain period of time after adding them to allow the records to propagate normally to DNS servers around the world. During this time, we can use the generated DNS records, such as "xxx.github.io", to access our pages through the GitHub domain name.

Finally when the records have propagated normally among DNS servers around the world, we can use our own domain name to access our website hosted on GitHub Pages.

Summary

To sum up, the time it takes for GitHub to allocate a domain name depends on the propagation time of DNS records, which usually ranges from 1 to 72 hours. If we urgently need to use our own domain name, there are some steps we can take to shorten the propagation time of DNS records.

For example, we can set the TTL value (ie "Time to Live") in the DNS management background to specify the survival time of DNS records. It is worth noting that although shortening the TTL value can speed up the update of DNS records, it will also increase the burden on the DNS server. Therefore, it is recommended not to set the TTL value too small.

In summary, while waiting for DNS records to propagate can be inconvenient, as users of GitHub Pages we must learn to be patient and focus on efficiency without neglecting quality. Only by fully understanding the characteristics and usage of GitHub Pages can we truly master this powerful tool and use it in our creation and development work.
