00:04 | in order to access the website when clicking on the domain name, you need to point your domain name to your server's IP, a static IP |
00:06 | if you have a dynamic IP: - either use a DDNS = a Dynamic DNS (free or paid) or - speak with your ISP to give you a static IP |
00:12 | the Dynamic DNS will manage the change of your dynamic IP, meaning that when IP changes, the new IP propagates instantly keeping your website alive. The Dynamic DNS DDNS is just a DNS service which uses short TTL values. |
00:20 | start by choosing a free DDNS: e.g. dnsexit.com, randomly chosen for example purposes Sign up for an account |
00:35 | then Log in to your Account |
00:49 | select Dynamic DNS Service |
00:58 | DDNS: allows you to associate a domain name to dynamically changed IP address...when running a web site at home |
01:10 | Steps: 1. Sign up an account - we've already done that |
01:15 | 2. Register a new domain or use your existing domain: we've already done that: d0main1.com registered to Enom |
01:23 | 3. Create DNS for the Domain: a) let's switch ⁄add the NS(name servers) of our DDNS provider (dnsexit.com) to our domain (d0main1.com) at our Registrar account (Enom) |
01:35 | log in to your Registrar account (Enom in our case for d0main1.com) and add the NS of your DDNS |
02:10 | save the new name servers added |
02:23 | Setup DNS for the domain |
02:29 | for DNS Express: click here for a video tutorial |
02:47 | Enter the domain name |
02:52 | enable DDNS |
03:06 | enter your public external IP: you can verify it by accessing: www.ip-address.com/ip_tracer |
03:12 | d0main1.com automatically assigned to our external IP |
03:22 | make aliases for the domain: www.d0main1.com points to d0main1.com |
03:30 | specify mail servers for the domain |
03:36 | TTL = 2 seconds → almost instant DNS propagation |
03:39 | Save DNS for the domain |
03:43 | Verify DNS |
03:50 | 4. Install a DDNS Client: it will automatically detect your IP changes and update the IP of your domain (DDNS account) |
04:09 | we've downloaded and installed the IP Updater 2.0 because we're on Windows |
