Long story short, we are using 192.168. X.X IP addresses because this is best practice. The IETF has created three IP ranges for private networks, with Class C being the smallest and easiest to control and maintain. This is why most routers use exactly this IP range.
Why is 192.168 the default?
The IP address 192.168. 0.1 is the most common address to access and configure wireless routers from a web browser. It’s a default address because specific IP address ranges are reserved for different types of networks, and 192.168. 0.1 is reserved for networks such as your home LAN.
What does 192.168 mean?
192.168. 1.1 is a common factory IP address for a consumer-grade router. If the router is used for connecting to the Internet then all computers and devices which access the Internet through it will use this address as their default gateway.
Is 192.168 a private IP?
And don’t be surprised if you have a device or two at home with a so-called 192 IP address, or a private IP address beginning with 192.168. This is the most common default private IP address format assigned to network routers around the globe.
What is a 169 IP address?
Causes of 169 IP Address Error
When a Windows computer isn’t able to communicate with the DHCP server, something called Automatic Private IP Addressing (APIPA) kicks in. It assigns the computer an IP address that starts with 169.254. These IP addresses are only useful on local networks, not the internet.
Why is my IP public?
An IP address (or Internet Protocol address) identifies each networked computer and device on a network. When you sign up with Internet service and connect your modem, your ISP assigns you a public IP address. This address is how you communicate with all the other devices out there on the public Internet.
What is 10.0 0.0 8 mean?
A network numbered 10.0. 0.0/8 (which is one of those reserved for private use) is a network with eight bits of network prefix, denoted by /8 after the oblique. The 8 denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.
What is the most common IP address?
A common IP address is 192.168. 1.1. Each number can, technically, range from zero to 255. Routers differ from other computing devices in that they have (at least) two IP address: a public one and a private one.
What is a 10.0 0.0 IP address?
IP Address (10.0. 0.0) – It is the global addressing scheme used under Internet Protocol.The IP addresses are allocated to each device and are unique. IP addresses are 32-bit numbers with every 8 bits separated by a decimal.
What does it mean 192.168 0.0 24?
192.168.0.0 Refers to the IP adress /24 refers to the subnet. / 24 subnet is 255.255.255.0. 192.168.0.0/24 is common for home networks.
Why 127 is the loopback address?
The class A network number 127 is assigned the loopback function, that is, a datagram sent by a higher level protocol to a network 127 address should loop back inside the host. No datagram sent to a network 127 address should ever appear on any network anywhere.
What is the 172 IP address?
The address 172.16. 52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive. Class C networks use a default subnet mask of 255.255.
Is APIPA routable?
The Internet Assigned Numbers Authority (IANA) has reserved 169.254. 0.0-169.254. 255.255 for Automatic Private IP Addressing. As a result, APIPA provides an address that is guaranteed not to conflict with routable addresses.
Can you ping an APIPA address?
When using APIPA, it is possible to ping other computers on the subnet, but it is not possible to ping computers that are external to the subnet. Client applications can verify their address is unique on the LAN using Address Resolution Protocol (ARP).
What is WIFI IP?
In the System Preferences window, click the Network icon. Select your network connectionfor example, a Wi-Fi or wired connectionand then click the Advanced button at the bottom of the screen. In the Network window, select the TCP/IP tab. You’ll see your router’s IP address listed simply as Router.
Who gives IP address?
Your IP address is assigned to your device by your ISP. Your internet activity goes through the ISP, and they route it back to you, using your IP address. Since they are giving you access to the internet, it is their role to assign an IP address to your device.
Are IP addresses unique?
The interface, not the device, has zero or more addresses. A host may have multiple interfaces. Use the Network Information app on an Android phone and you’ll see that it has quite a lot of addresses.
How many IPv4 addresses are there left?
In fact, there are today about 4.3 billion IPv4-type IP addresses throughout the entire world.
What is CIDR notation?
CIDR notation (Classless Inter-Domain Routing) is an alternate method of representing a subnet mask. It is simply a count of the number of network bits (bits that are set to 1) in the subnet mask.The CIDR number is typically preceded by a slash / and follows the IP address. For example, an IP address of 131.10.
How many IP addresses are in a 16?
Subnet Cheat Sheet 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References

What is the 0.0 0.0 address?
In the Internet Protocol Version 4, the address 0.0. 0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target. This address is assigned specific meanings in a number of contexts, such as on clients or on servers.
