What Are Private IP Addresses?

IP or Internet Protocol addresses are numerical signs which can be assigned to every device attached to the internet. A device, it could be a computer or even a different computer which requires internet connection to operate properly, must have an IP address used on it in order to be able to access the net. There is a complete of 4294967296 or (2^32) IPs available, and the majority of the are public IPs. Public IPs are in reality those that directly access the net and are utilized by devices built online. IPs possess a format of x.x.x.x, where x equals all numbers between 0 and 255. Therefore, an example IP address is 67.23.121.5 or 173.21.234.112.

A relatively small number of IP numbers is available to private use. These reserved blocks are meant to be utilized by private networks and routers internally and they'll stop accustomed to access the net directly. There are several reserved blocks, however the most favored ones will be the 192.168.x.x and 10.x.x.x blocks. The former is widely utilized by many router manufacturers and is basically a standard today, while the latter isn't used anymore. In order to access a router's configuration panel, an individual IP number is used. For example, Cisco and Netgear routers utilize 192.168.1.1 IP number his or her default. Others manufacturers like Billion use 192.168.1.254. Some producers use 192.168.100.1 and 192.168.2.1.

The IPv4 strategy is the cornerstone of the internet as you may know it today. However, because of the boost in internet usage over the last ten years, we have run out of IP addresses. As of 2010, there isn't any more free available IPs. That means that they all are reserved and bought by various users (telecom companies, serves, governments). In order to overcome this problem, some other system called IPv6 is made and it is designed to solve this problem. IPv6 is an extremely advanced system which uses different nomenclature in comparison to IPv4 and possesses an overall total of 2^128, that is roughly 3.4x10^38. However, the switch between those two systems will need time, because it is a totally different system. However, once we switch onto IPv6, we can't be running out of addresses anytime soon, since there will probably not be enough devices to fill in the IPv6 quota.
