Static Ip Vs. Dynamic Ip

Difference Between Static Ip and Dynamic Ip

An IP address is briefly explained as the Internet’s answer to the phone number. For network devices to communicate together it is necessary for them to be able to find the right network device, this has been solved by introducing IP addresses. IP address is an abbreviation for Internet Protocol address. Surfing the Internet will always leave its IP address.  It is your Internet service provider (ISP) who knows what IP address belongs to you. If the IP address is being used  for a crime then police can request to receive data on who used the IP address in the relevant period. It is therefore important to have control of what goes on at home network, especially now when everyone is having wireless networks.

For example if a home network is having following Ip’s

  • 193.69.165.21 is the public IP address.
  • 192.168.1.1 – router / modem.
  • 192.168.1.2 – Network Sprinter.
  • 192.168.1.3 – Desktop PC.
  • 192.168.1.4 – Laptop.

When some of the network devices are attached to the local network while surfing the Internet, it would appear that traffic comes from 193.69.165.21. The website that you surf will not be able to see which machine on the local network is being used for browsing.

Static IP means that you have a fixed IP address. This means that even if you reboot, the network device will still keep the same IP address.

Dynamic IP means that you have a variable IP address. It means that when you restart the network device there may be a risk of getting a new IP address. Most of the DHCP servers today still remember the IP address the network device had last time when it was connected and will therefore try to assign the same IP address again.

Internal IP is the address they have on their local network. Most home network has a router / modem for the connection with network device. Router / modem will then hand out internal addresses for use on the local network.

External IP is the public address that appears when you surf the Internet. It is the address that points back to your router, which in turn directs the traffic on the local network.

DHCP, Dynamic Host Configuration Protocol is used in computer networks to assign IP addresses and other network parameters for devices that are connected automatically.
