Ip address

Anonymous

Everyone who are living in this world has it’s own unique identity. The unique identity maybe his/her home address or maybe his/her ID card number. But can you ever think what is your identity on the internet??? So, don’t worry today i will answer this question in more simple words.

IP Address:

IP address stands for Internet Protocol Address. It can provide your identity on the internet. It’s also enable the devices to communicate with each other on IP Based Networks like internet. The example of IP address is (231.23.764.123). The working process of this technology is very simple. When any device is connected to the internet. A unique numerical identity is assigned to it. When two devices wanted to share the information. The data are firstly converted into packets and then transferred to the destination device containing IP address of both devices.

‘IP’ stands for ‘Internet Protocol’.

Version Of IP ADDRESS:

There are two versions of IP address which are introduced now a days. The first one is IPv4 and the second one is IPv6.

IPv4:

IPv4 stands for Internet Protocol Version 4.
IPv4 addresses are normally expressed in dot-notation xxx.xxx.xxx.xxx where xxx is a value from 0 to 255.
It is a technology that allows the devices to communicate with each other. IPV4 addresses have 4 bytes (32 bits) in length. These bytes are typically called octets and for the sake of readability, these bytes, bits, and octets are written in what’s called dotted decimal. Dotted decimal separates each octet of the IP address with a decimal point.

For example, a typical IP address (IPv4) seen by a computer in binary notation is:

11000000.10101000.00000001.00000000

That translates into dotted decimal as:

192.168.1.0

IPv6: IPv6 stands for Internet Protocol Version 6. It is more advanced then IPv4 but it’s working is same like IPv4. It’s enable more devices to communicate with each other. The IPv6 address size is 128 bit. The example of IPv6 is (3FFE:F200:0234::48).

Difference between Static and Dynamic IP address:

Static address is one that you configure yourself by editing your computer’s network settings. This type of address is rare, and it can create network issues if you use it without a good understanding of TCP/IP.

Dynamic addresses are the most common. They’re assigned by the Dynamic Host Configuration Protocol (DHCP), a service running on the network. DHCP typically runs on network hardware such as routers or dedicated DHCP servers. Dynamic IP addresses are issued using a leasing system, meaning that the IP address is only active for a limited time. If the lease expires, the computer will automatically request a new lease.

Difference between Private and Public IP address:

Private IP address of a system is the IP address which is used to communicate within the same network. Using private IP data or information can be sent or received within the same network.

Public IP address of a system is the IP address which is used to communicate outside the network. Public IP address is basically assigned by the ISP (Internet Service Provider).

PRIVATE IP ADDRESS
1.Scope is local.
2.It is used to communicate within the network.
3.It works only in LAN.
4.It is available in free of cost.
5.Private IP can be known by entering “ipconfig” on command prompt.

PUBLIC IP ADDRESS
1.Scope is global.
2.It is used to communicate outside the network.
3.It is used to get internet service.
4.It is not free of cost.
5.Public IP can be know by searching “what is my ip” on google.

IPv4 Address Classification

There are 5 classes of IPv4 addresses, labeled A through E. The class of the IP address is determined by the first 4 bits.

Class A — IP addresses are in this class if their first bit is a 0. In dot-notation, this is the range 0.0.0.0 to 127.255.255.255 . The first 8 bits represent the network prefix and the rest represents the host identifier. For example, 127.42.13.69 has network prefix 127 and host identifier 42.13.69 .
Class B — IP addresses are in this class if their first two bits are 10 . In dot-notation, this is the range 128.0.0.0 to 191.255.255.255 . The first 16 bits represent the network prefix and the rest represent the host identifier. For example, 129.42.13.69 has network prefix 129.42 and host identifier 13.69 .
Class C — IP addresses are in this class if their first three bits are 110 . In dot-notation, this is the range 192.0.0.0 to 223.255.255.255 . The first 24 bits represent the network prefix and the rest represent the host identifier. For example, 196.13.42.69 has network prefix 196.13.42 and host identifier 69 .
Class D — IP addresses are in this class if their first four bits are 1110 . In dot-notation, this is the range 224.0.0.0 to 239.255.255.255 . These addresses are used for multi-casting protocols (ie. when a single packet can be sent to multiple hosts in one action)
Class E — IP addresses are in this class if their first four bits are 1111 . In dot-notation, this the range 240.0.0.0 to 255.255.255.255 . These addresses are reserved for future and experimental use.
