How to convert ip address to digital address

This question makes no sense.

Please explain what you mean by "digital address".

I'm not entirely sure I understand your question but I can explain a little about IP addresses and another form of address used by network interfaces. Any functioning network interface actually has two addresses with which it can be accessed. The one most people are familiar with is it's IP (Internet Protocol) address. This address is assigned either manually by the user or automatically through a procedure called DHCP. If a computer is set to get an address through DHCP then when it boots up it broadcasts a request for an IP address. The DHCP server the responds, sending an address and other information needed to use the network. If you have a router at home then usually it is running a DHCP server which assigns local IP addresses to computers connected to it. If your computer is connected directly to a cable or DSL modem then your internet service supplier is running their own DHCP server. An IP address consists of four eight bit numbers, commonly expressed as a 'tuple' of four decimal numbers. Since an 8 bit number can only have a value from 0 to 255, each number of an IP address can only be from 0 - 255. A valid IP address might be 192.168.0.1 or 8.8.8.8 or 74.125.95.147 however 514.240.1.321 is not valid. There is another address used by network interfaces which is a unique address assigned by the manufacturer called a MAC (Media Access Control) address. IP is not the only networking protocol, other protocols used different methods of addressing individual computers on a network. MAC addresses are the lowest level of network addressing. A MAC address consists of six eight bit numbers, most often expressed as twelve hexadecimal digits, often separated by colons. A hexadecimal digit can only be 0 - 9, or A, B, C, D, E, or F. An example is 00:10:dc:e6:56:e6. All network interfaces, wired or wireless, have a permanent MAC address assigned to them. Some devices, such as routers, can override their assigned address. If you look at a network interface card or a wireless card the MAC address is normally printed somewhere on it similar to a serial number. Why use both? Since IP addresses are easy to change and can be reassigned at will it's more flexible. If a network interface on a computer failed a new interface would have a different MAC address but the computer could still be assigned the same IP address. A good analogy would be the difference in usage between a vehicles VIN (Vehicle Identification Number) and it's license plate; if you move to another state (or network in computer terms) then you need to get a different license plate. Technically, both an IP address and a MAC address are digital addresses used to locate a and communicate with a computer on a network. Hope this helps.
