== Why Do You Need Dynamic DNS? == '''Your IP address changes.''' Your IP address is like your home address or phone number. You want this to be static - as in, doesn’t change. Imagine if all of the road names and highway exits changed each day, or if your friend’s phone number changed every day. This would be a mess. How would you know who to call? It would be very confusing. This is how it is when you have a dynamic IP. Most of you setting up a home server likely have a residential internet plan from providers like Spectrum, AT&T, or Verizon. Unlike professional hosting services with static IPs, residential plans assign dynamic IP addresses that change as often as the relationship partners of people with borderline personality disorder. This can be a problem when you want to access your home network remotely. What if you had a speed dial button that automatically kept track of that friend’s changing number, and just allowed you to reach your friend every time you pressed on their name? That’s how a dynamic DNS works. Even if you DO manage to memorize 33.484.382.1, imagine having to memorize a new number every week. Or ''every day!'' And what if it changes in the ''middle of the day?'' Imagine having to check your IP address every day, or calling home & going ''“hey honey, can you go to whatismyip.com and give me the number so I can add something to my calendar? Thanks!”'' That would be horrible. What you want to do is go to ''chrisserver.mooo.com'' or ''mysite.ddns.net'' and it takes you right to your server, every time. This is possible because someone else can do the work of keeping track of your router’s IP address and assigning it to that domain name. Or, something. That thing is a '''dynamic DNS provider.''' This is where '''Dynamic DNS''' comes in handy. It automatically updates a friendly hostname to point to your current IP address, so you can always access your home network using a consistent address. <span id="setting-up-freedns"></span>
