Private ip address range list

PRIVATE IP ADDRESS PUBLIC IP ADDRESS; Scope is local. Scope is global. It is used to communicate within the network. It is used to communicate outside the network. Private IP addresses of the systems connected in a network differ in a uniform manner. Public IP may differ in uniform or non-uniform manner. It works only in LAN.

Private IP (Internet protocol) address blocks are the IP addresses most often used for private networks. Most networks use addresses in one of these ranges: 10.0.0.0 to 10.255.255.255 172.16.0.0 to 172.31.255.255 192.168.0.0 to 192.168.255.255 Public IP addresses will be issued by an Internet Service Provider and will have number ranges from 1 to 191 in the first octet, with the exception of the private address ranges that start at 10.0.0 for Class A private networks and 172.16.0 for the Class B private addresses. Class A private IPv4 addresses starts from 10.0.0.0 to 10.255.255.255. 10.0.0.0/8 is the network IPv4 address and10.255.255.255 is the directed broadcast IPv4 address. Consists of total 16,777,216 IPv4 Addresses (‭16,777,214‬ usable IPv4 addresses). According to standards set forth in Internet Engineering Task Force (IETF) document RFC-1918, the following IPv4 address ranges are reserved by the IANA for private internets, and are not publicly routable on the global internet: 10.0.0.0/8 IP addresses: 10.0.0.0 – 10.255.255.255; 172.16.0.0/12 IP addresses: 172.16.0.0 – 172.31.255.255 Address ranges to be use by private networks are: Class A: 10.0.0.0 to 10.255.255.255; Class B: 172.16.0.0 to 172.31.255.255; Class C: 192.168.0.0 to 192.168.255.255; An IP address within these ranges is therefore considered non-routable, as it is not unique. Any private network that needs to use IP addresses internally can use any address

Jul 03, 2017 · The easiest way to find your public IP address is by asking a website, since that website sees your public IP address and can tell it to you. We recommend using the site ip4.me because it’s quick, ad-free, and will show your IPv4 address—the four part address you’re most likely looking for—rather than the more complicated IPv6 address

Nov 18, 2018 · A public IP address is globally unique, and can only be assigned to a unique device. What is private IP address? A private IP address is the address space allocated by InterNIC to allow organizations to create their own private network. There are three IP blocks (1 class A, 1 class B and 1 class C) reserved for a private use. May 29, 2019 · In the ’80s, when the IPv4 protocol was created, it introduced 32-bit numerical IP addresses. These equated to approximately 4.3 billion unique IP addresses. However, it was soon evident that we will need more. The problem was solved by introducing private IP addresses and Network Address Translation (NAT). NAT sits on your router and directs Jun 30, 2019 · To this end, a range of IP addresses have been specified to be private and only used on Internal Networks. These networks are not to be connected 'directly' to the Internet. These are then Private IP addresses. The remaining addresses are then Public IP addresses and devices with these addresses can be directly connected to the Internet.

The IPv6 address is similar to IPv4 in concept, but it provides far more than enough unique IP addresses for worldwide networking devices such as computer, router, data switch, etc. This is now a detailed introduction on what an IPv6 address is, and discuss differences between public and private IPv6 addresses.

A private IP address is a numerical identifier that is used by software and hardware to communicate in a private network. Private IPs are intended to be unreachable by public networks such as the internet. The following are common examples of a private IP. Feb 20, 2018 · IPv4 – Most widely used IP to connect your devices through the internet. It uses a 32-bit address scheme, meaning it has over 4 billion available addresses. It is defined by three address blocks. 24-bit block : Ranges from 10.0.0.0 – 10.255.255.255 Nov 18, 2018 · A public IP address is globally unique, and can only be assigned to a unique device.
