When you do not leave your modem and router on 24-7, chances are that your public IP address will change. As I had noted in how to host multiple website at home<\/a>, a public IP address is needed for HTTP clients<\/a> to reach your HTTP servers<\/a> at home.<\/p>\n

On the other hand, a domain name allows us to map some meaningful English characters to that public IP address. Therefore, it is easier to access our servers with a domain name rather than an IP address.<\/p>\n

Although you can get a free subdomain from a dynamic DNS provider, getting your own domain name from a domain registrar like Namecheap<\/a> can be better. On one hand, you get your own online branding for establishing yourself or your business on the Internet. On the other hand, you are resilient to having your domain shutdown by the dynamic DNS provider for any reasons that is beyond your control.<\/p>\n

Previously, I shared why Namecheap is the best domain name registrar for hosting your web server at home<\/a>. One of the reasons is that Namecheap provides dynamic DNS for us to update the host records of our domain whenever our public IP address changes. Since Raspberry Pi 3 is an affordable, small and energy efficient single board computer<\/a>, you can get it to use Namecheap Dynamic DNS service to update your domain when your home's public IP address changes. <\/p>\n

In case you need it, this is how to get Raspberry Pi 3 to use Namecheap dynamic DNS to update your domain when your home's public IP address changes.<\/p>\n

Getting a cheap domain name from Namecheap<\/h2>\n

In case you are looking to buy a domain, you can head over to Namecheap's promotions page<\/a> to check out their current promotions. In addition, you can checkout their coupons page<\/a> to get your domain with some discount. <\/p>\n

Adding the necessary host records for your domain<\/h2>\n

After you had gotten your domain name from Namecheap, you will need to setup some host records for your domain<\/a>. <\/p>\n

The host records page for your domain should look like the following:<\/p>\n

\"host<\/p>\n

Note that if you miss this step, you will find the following error message in \/var\/log\/syslog<\/code> when you run DDClient later<\/strong>:<\/p>\n

\r\n\/var\/log\/syslog:Oct 13 12:35:08 raspberrypi ddclient[5591]: WARNING:   <?xml version="1.0"?><interface-response><Command>SETDNSHOST<\/Command><Language>eng<\/Language><ErrCount>1<\/ErrCount><errors><Err1>No Records updated.

Seeing the above error message will mean that your Raspberry Pi 3 was not able to update the public IP address record for your domain.<\/p>\n
Enabling Dynamic DNS for your domain in Namecheap dashboard<\/h2>\n
After you had gotten your domain name from Namecheap, you will need to enable Dynamic DNS for your Namecheap domain<\/a>. Once you had gone through the steps in the article, note down the Dynamic DNS password<\/strong> for updating your public IP address changes with Namecheap.<\/p>\n
