What are IP classes used for?
IP addresses from the first three classes (A, B and C) can be used for host addresses. The other two classes are used for other purposes – class D for multicast and class E for experimental purposes. The system of IP address classes was developed for the purpose of Internet IP addresses assignment.
How many subnets are in Class A?
The two bits added to the network part from the host part can have four possible values in second octet of a Class A network , 00, 01, 10, and 11. That means, we can get four networks if we do a 2-bit subnetting on a Class A network. Ths subnet mask to use for Class A network 2-bit subnetting is 255.192. 0.0.

Can 2 devices share the same IP address?
Two computers should never have the same IP address if they’re on the same network. If they do, results are unpredictable. What happens if two computers have the same IP address? An IP address uniquely identifies every computer on the internet.
What is a 255.255 255.0 subnet?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
What are the 2 types of IP address?
‘IP’ stands for ‘Internet Protocol’. There are two versions of IP that currently coexist in the global Internet: IP version 4 (IPv4) and IP version 6 (IPv6). IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long.
Is IP address WIFI or device?
The main connection from your service provider will be assigned a unique IP Address (unique to the World). Each device connected to the router/modem will be assigned a local IP address including the router (which is usually 192.168.

DO devices have IP addresses?
All computers and other devices connected to a network, such as smartphones, tablets, and fax machines, have a unique IP address. No two computers on the network may have the same IP address. Without the IP address, computers and mobile devices would not be able to communicate with each other.
What is a Class A subnet?
Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet. The address 10.52. 36.11 is a class A address. Its first octet is 10, which is between 1 and 126, inclusive.
What are the 3 major classes of an IP network?
Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.
Why is 192.168 always used?
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.
Can your IP address be used by someone else?
Neither your ISP nor anyone else can actually tell what you are doing on the Internet. But they can follow the activity of your public IP address—the one your router uses to access the Internet. … Anyone can use it to discover your general location (your neighborhood, not your house) and your ISP.
How many subnets are in a Class A IP address?
The default subnet mask for Class A IP address is 255.0. 0.0 which implies that Class A addressing can have 126 networks (27-2) and 16777214 hosts (224-2).
What is 192.168 called?
1.1 – Computer Definition. The common default IP address of a router. Although it can be changed to another private IP addressing space, most of the time, the 192.168 range is used, and the default router address is left as is.
Is 172 a private IP address?
Note that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet. … x.x.x IP address may have difficulty reaching some sites on the global Internet.
