There are other systems, such as DNS and Avahi, to help route one computer to another, but when those are unavailable or undesired for any reason, the IP protocol is what you use. For example, the public IP address for is 54.204.39.132Īn IP address is the most direct route to a computer over a network. Each website has a domain name mapped to a public IP. These are often used to determine geolocation.Ī private address costs money because they are unique, limited, and accessible from the Internet. Ranges from 0.0.0.0 to 255.255.255.255, except for private IP addresses and few unusable or reserved IPs. Public addresses are used to connect to external networks. Users don’t need to pay extra to obtain a private address. Not unique: the same private IP can be used in two different networks.Įach router comes with a private IP address, which multiple devices can connect to. Not globally reachable, and cannot be searched globally. Local addresses are only used within an internal network. PAT is most widely used in residential wireless routers, which we use to connect to the Internet. Here, instead of assigning a public address to each device, a single public address is allocated to the external side, and private addresses are assigned to each device within the internal network. That's because of a concept called PAT, which allows for a single public IP address to be translated from multiple (generally all) private IP addresses using port numbers. With a total of 2^32 IPv4 addresses, out of which approximately just 3.7 billion are public addresses, there are literally more people and devices than there are IP addresses. In dynamic NAT, a private IP address is mapped to a public IP but from a pool of public IP addresses. In static NAT, one private IP is mapped to one public IP.

NAT is a translation of a private IP to a public one, and consists of three major types: static, dynamic, and PAT. Public addresses are necessary for establishing external connectivity to other networks, most notably the "Worldwide Web" (www) of the Internet.

Private addresses are used in Local Area Networks (LAN). To understand the significance of public and private IP addresses, let's have a look at a concept called NAT (Network Address Translation) and PAT (Port Address Translation). In this example screenshot, my IPv4 address is 10.1.1.2 and the gateway is 10.1.1.1. First, go to your Activities screen and type Network (for a wired connection) or Wi-Fi (for wireless). If you're using Linux, you can find your IP address using some basic desktop utilities. Also, some of the noted commands use a third-party website to get the IP Finding your IP address in the GNOME desktop Note: Some utilities need to be installed on your system based on the Linux distro you are using.

(Fedora) Wifi-Settings→ click the setting icon next to the Wifi name that you are connected to → Ipv4 and Ipv6 both can be seen.

The following commands will get you the private IP address of your interfaces: The following commands will get you the IP address list to find public IP addresses for your machine: These are private IP addresses, but both would have the same public IP address. For example, my laptop is connected with the IP address 192.168.0.5, and my phone is connected with 192.168.0.8. All the devices connected to the same WiFi have private IP addresses locally identified by the range provided above. Your WiFi router has a public IP, which is the WAN (wide-area network) IP address, and it will be the same for any device connected to that WiFi. IPv6 was introduced to tackle the foreseeable exhaustion of IPv4 addresses in the near future.Īs a network engineer, I recommend not sharing your machine’s public IP address with anyone. The total number of bits is 128, which means there are 2 ^128-340 undecillion!-possible IPv6 addresses. IPv6 addresses have a more complex format using hex numbers. There are 2 ^32 (approximately 4 billion) possible IPv4 addresses. IPv4 addresses have the format x.x.x.x, where x=0 to 255.
