What is a Static and Dynamic IP address?

You may have had an IP address blocked and required to get in touch with the support team to unblock the IP. After the IP being unblocked a few days, weeks months later you find that your IP is blocked again. You may have gone to a site such as and reported a different IP address than the original one. This will be because you have a dynamic IP address.

So, let’s find out what an IP address is and what the difference between a static and dynamic IP.

What is an IP address?

An IP address is assigned to every computer on an Ethernet Network. Like the numbers in a phone book, an IP address identifies network computers. It helps traffic flow between computers/servers because each one has its own IP address.

What is a dynamic IP address?

A dynamic IP address is exactly how it sounds, dynamic IP addresses are subject to change, sometimes at a moment’s notice. Dynamic addresses are assigned, as needed by Dynamic Host Configuration Protocol (DHCP) servers.

Dynamic IP addresses are generally implemented by internet service providers and networks that have many connecting clients or end-nodes. One of the primary reasons behind having dynamic IP addresses is the shortage of static IP address on IPV4. Dynamic IP addresses allow a single IP address to be shuffled between many different nodes to circumvent this problem.


  • Security
  • Automatic network configuration
  • Unlimited IP addresses.


  • Less Reliable.
  • More potential downtime.
  • Limit remote access.

What is a static IP Address?

Static IP address, or fixed IP address, is an IP address that never changes. Once your device is assigned a static IP address, that number typically stays the same until your router/modem is reset to filter a new IP address.

Static IP addresses are assigned by Internet Service Providers. Your ISP may or may not allocate you a static IP address depending on the nature of your service agreement.


  • Easier management
  • Faster download/upload speeds:
  • Stability


  • Easier to hack.
  • Each Static IP must be manually configured.
  • Some static IP address can become obsolete.
