What is IP address?
Let us check out what is the IP address...
What Is an IP Address?
IP stands for Internet Protocol. An IP address is a binary number that uniquely identifies computers and other devices on a TCP/IP network. IP (pronounced eye-pea) stands for Internet Protocol. Every machine in a network have their own unique identifier including computers, phones, printers, and Internet of Things (IoT) gadgets, receives an IP address. Just like our fingerprints that are different from each other even the twins.
What are the importance of an IP address?
An IP address serves two primary functions. It is used as an interface identification for a network of machines(even a machine needs ID😃) Besides, it also serves to provide a location of that machine, much like a physical address for a home or business.tat is how we can detect who and where any activities using the network is done. Because an IP address is a unique identifier, it allows computers to send and receive information to and from specific computers in a given network. Imagine, how can information transfer occur if the is no specific address. If we can related to our daily life, a postman cannot send the mail or parcel with no address.
What are the types of IP address?
IP address can be divided into two, which are public address and private address. Public address is considered as any valid address assigned to any user, and the organizations who is responsible for registering IP ranges called Internet Service Providers (ISPs),and this address is unique.In simpler words, public IP address is for use on the Internet or other wide area network (WAN). Meanwhile, private address is assigned to a device on a private TCP/IP. For instance, Local Area Network (LAN) is only accessible within the LAN.
Two IP addressing standards are in use today. The IPv4 standard is most familiar to people and supported everywhere on the Internet, but the newer IPv6 standard is gradually replacing it. IPv4 addresses consist of four bytes (32 bits), while IPv6 addresses are 16 bytes (128 bits) long.
An IPv4 address consists of a group of four numbers, each between 0 and 255. Computers store and work with an IP address as one combined (binary) value, but network devices displays them in human-readable forms. IPv4 uses dots to separate the individual numbers that range from 0.0.0.0 to 255.255.255.255. IPv6 uses colons instead of dots to separate the numbers and also uses hexadecimal rather than decimal digits.
To simplify:
IP address and domain name. What is the connection between these two?
IP address is an actual set of numerical instructions. It communicates exact information about the address in a way that is useful to the computer but cannot be understand or used by humans.
Domain Name System (DNS) acts as translator between IP address and domain name.
Domain names function on the Internet in a manner similar to a physical address in the physical world that can be understand by humans. Each part of the domain name provides specific information. For example, www.blogger.com, is comprised of three essential parts:
- .com - This is the top-level domain.
- .blogger. - This is a sub-domain.
- www. - This is a sub-domain prefix for the World Wide Web. The original use of this prefix was partly accidental, and pronunciation difficulties raised interest in creating viable alternatives.
Here are some examples of top-level domain (TLD):
How can we convert an IP address from 32-bits of binary numbers into dotted decimal format?
01011110000101001100001111011100
Step 1: divide the binary number into 4 groups of octets.
a) 01011110
b) 00010100
c) 11000011
d) 11011100
Step 2: since every group is octet,
2⁷ 2⁶ 2⁵ 2⁴ 2³ 2² 2¹ 2⁰
128 64 32 16 8 4 2 1
Step 3: Compare the sequence and get the total values of meaningful binary number which is 1
a) 64 +16+8+4+2=94
b) 16+4=20
c) 128+64+2+1=195
d) 128+64+16+8+4=220
Step 4: Write in decimal notation
94.20.195.220
2⁷ 2⁶ 2⁵ 2⁴ 2³ 2² 2¹ 2⁰
128 64 32 16 8 4 2 1
Step 3: Compare the sequence and get the total values of meaningful binary number which is 1
a) 64 +16+8+4+2=94
b) 16+4=20
c) 128+64+2+1=195
d) 128+64+16+8+4=220
Step 4: Write in decimal notation
94.20.195.220
