There are two ways of getting IP address from our ISP (Internet Service Provider). First one is which you get from your ISP it is a static IP which you cannot change. And other way is by dialling the username and password provided to you by your ISP which you have to dial through your PC or Router to get an IP from your ISP. If you have been provided with the static IP For e.g. (24.213.45.122) then this cannot be changed else you ask for the other IP address from your ISP.

And the other one is which you get it from your ISP after dialling a correct Username and the password. This IP address is dynamically given to your dialling source whether a PC (Server or a gateway), a Modem or a router. I depends upon your network structure that what source you are using for dialling purpose. This IP address can be changed by restarting the connection again for e.g. (If you are using your wireless router for dialling then simply re-start your router or open the admin settings of your router and re-start the connection from there). In this way you can change your IP address provided to you by your ISP.

Note:-If you want to login to a proxy site and you are not able to login because you have already used the services from that site then use various IP soft wares to change your proxy settings of your connection.

Don’t ever fiddle with your ISP IP address otherwise your account will be banned in case of static IP address.

2. LAN IP Address

(a)If DHCP is not enabled

This IP address is provided to your PC by your LAN gateway. It is your local area network address provided to you by the gateway in case of servers or by your Home Router or Modem. It is your LAN IP. That depends on your router settings that DHCP is enabled or not. If DHCP (Dynamic Host Client Protocol) in your router configuration is not enabled then you have to enter the IP address in your PC/Laptop LAN card settings. The IP address you enter must be of the same series with your gateway’s IP address.

You can change your LAN IP any time by opening your LAN card properties then select protocol IPv4 properties here you can enter the IP Address(Should be of the same series as your gateway has), enter subnet mask, Gateway address(your modem’s or router’s IP address whichever is dialling), then comes Primary DNS(Domain Name Server) and Secondary DNS. Here you have to enter your ISP server’s address. You can get it from your ISP only.

(b)If DHCP is Enabled

If DHCP is enabled in your gateway (Router or Modem) then you need not to enter the IP address in your LAN card properties. IP address is assigned to your PC/Laptop automatically with the preferred DNS.
