There are actually certain numbers of IP addresses that are reserved for a specific reason or purpose. Not all IP addresses can be used for hosts; in fact, there are some IP addresses that are assigned by the Internet Assigned Numbers Authority (IANA) for special purposes.
In this article we are going to discuss special purpose IPs:
#1. IP: 0.0.0.0
This IP has special meaning on the computer networks. A computer usually shows this exclusive IP when your computer is disengaged with a TCP/IP network. With this exceptional IP, Your computer will not be able to reach or converse with any other computers over IP.
Sometimes, TCP/IP software applications also use 0.0.0.0 as a programming procedure in order to observe the traffic over the network from any legitimate IP address.
When connected, the nodes don’t employ this address, but rather, the information running over IP usually embrace 0.0.0.0 within the header when the origin of information is unidentified.
#2. IP 240.0.0.0
This IP comes under IPv4’s class E network (240.0.0.0/4) and carries around 268 million addresses. The IP addresses in this class are set aside for the purpose of future and experimental use.
Since IPv6 has been insisting that they have been running out of address space, IPv4 still makes a solid claim to being “Reserved for future use”. In future when IPv6 is widely implemented IPv4 will be utilized.
#3. IP: 127.0.0.1
IP 127.0.0.1is computers’ loopback address, this inimitable purpose address is reticent for use on each computer. Network utilities may use this address in order to access any local computer’s TCP/IP network resources.
Each message passed to loopback IP address such as 127.0.0.1 is not reached outside to the local area network (LAN) but rather, they are reached through the design re-routed by your computer’s self-network adapter. Normally each of the IP address that comes in between 127.0.0.1 – 127.255.255.255 is kept for private users.
If you need to find “my live IP address” one of the easiest ways is by using a website such as “What is my IP”.
#4. IP 10.0.0.1
It is often times referred to as a “default gateway address” since it normally presents the local part of a router’s link with the Internet. This IP address is a default for a number of network routers such as Cisco’s routers. A network server can use IP 10.0.0.1 as well.
Business networks than households normally use it. The 10.x.x.x, as well as the 192.168.x.x ranges, are private IP addresses.
#5. IP 220.127.116.11
The IP address in the range of 18.104.22.168 – 22.214.171.124 is kept for particular “well-known” multicast addresses. These IP addresses are allocated by IANA and chosen for multicasting barely on the local network.
A Multicast address is used in order to process datagram or frame anticipation to be used as a multicast to a chosen network. In addition, the range for multitasking address starts from 126.96.36.199 and ends to 188.8.131.52.
These are the following five IP address allotted by the Internet Assigned Numbers Authority (IANA) for special purposes.
