What is DNS & Dynamic DNS?
The techy stuff broken down...
No-IP takes your dynamic IP address and points it to a static hostname or subdomain. With our Free Dynamic Update Client installed at the location, No-IP checks for IP address changes regularly. When your IP address changes, we update your hostname with the correct IP address. No downtime necessary.
How does DNS work?
DNS stands for Domain Name System
It’s like the white page directory for the Internet. You supply a name, DNS supplies a number. The name in this case is specifically a hostname and the number is an IP address. Without DNS you would have to remember every IP address of every website you want to visit.
1. Enter Desired Domain (or website)
Alice wants to visit the website www.noip.com so she types it in the address bar in her favorite web browser.
2. Computer Looks Up the IP Address
Her computer contacts her ISP to get the IP address for noip.com. Her ISP’s DNS server doesn’t know the IP address, so it checks with the domains root servers.
3. Website Loads
The root servers tell Alice's ISP the IP address of No-IP’s nameservers and her ISP looks up noip.com. Her computer receives the IP address and connects to the website.
What is Dynamic DNS?
Dynamic DNS makes a dynamic IP address act as though it's static
Why? Dynamic IP addresses can make remote access difficult, dynamic DNS simplifies it by pointing an easy to remember name (yourname.no-ip.org) to your IP address.
How? Create an easy to remember hostname, then download our Dynamic Update Client (DUC) and run it on your computer. When your IP changes, the DUC updates your hostname.
The result? Your hostname stays active with your current IP address so you are always able to access your computer or device remotely.
IP stands for Internet Protocol
An IP address is a unique number that allows computers to locate each other on a network. The Internet is a big network and uses IP addresses to route communication to the proper host. The IP in IP address stands for Internet Protocol. An IP address looks like this: 184.108.40.206.
The term hostname refers to the unique part that identifies a host on the Internet
In www.noip.com, www is the hostname. In that same example, noip.com is the domain name. The host portion prepended to the domain name is often referred to as the hostname and that is how we use the term here. So, in summary, www is the host, noip.com is the domain, and www.noip.com is the hostname. Hostnames are often used to mark different locations, or internal pages on a website (for example: blog.yourwebsite.com).
What else is there to know?
When you choose us, you choose the best
When you choose No-IP as a dedicated managed DNS provider, your website's DNS is not only hosted at 2 locations, it is hosted at 17 locations across the globe. This means that if there is some sort of outage, your website won’t experience any downtime. The main complaint of downtime is how much it can potentially cost a business. If your website handles e-commerce, or you take in a great amount of leads and new customers from your website, you should really think of adding a managed DNS provider. How much would downtime cost your business?
