What class is a 172 IP address?
class B addressThe 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..
What is the difference between Class A Class B and Class C networks?
If the address is written in decimal format, the first number determines the address. If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B. If the first number is between 192 and 223 inclusive, the address is class C.

What is a Class A subnet?
A Class A IP address reserves 8 bits for a network with 24 bits dedicated to hosts. Its IP address spans from 0 to 126. The Class A subnet mask is 255.0. 0.0. Accordingly, Class A IP addresses are best used to serve incredibly large networks.
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.
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.
Which of the following is the best definition of IP spoofing?
IP spoofing is the creation of Internet Protocol (IP) packets which have a modified source address in order to either hide the identity of the sender, to impersonate another computer system, or both.

What is a Class A IP address?
In Internet Protocol version 4 (IPv4), a unicast address in the range 1.0. 0.1 to 126.255. 255.254. Class A addresses are identified by a beginning 0 bit.
DO devices have IP addresses?
Every device on the Internet has two IP addresses: a public and a private one. In your home, your router uses your public IP address—assigned by your ISP—to connect to the Internet. Your router assigns private IP addresses to PCs and other devices to create a local network.

Can two devices have the same IP?
The Question As I understand it, two computers cannot have the same public (external) IP address unless they are connected via the same router. If they are connected via the same router, then they can have (share) the same public IP address yet have different private (local) IP addresses.
What is class A network range?
Class A Address Thus the first octet ranges from 1 – 127, i.e. Class A addresses only include IP starting from 1. … x.x.x is reserved for loopback IP addresses. 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 a Class C 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. So: IP address 192.168.
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.
Can 2 devices have the same IP address?
Although both computers are sharing the same public IP address and accessing the Internet at the same time, the router knows exactly which computer to send specific packets to because each computer has a unique internal address. In that case 2 or more computers can get same IP.
Can your IP address be used by someone else?
Someone can use your IP to hack your device If someone knows your IP address, they can try to connect to your device directly. Every device uses ports, that allow various services to connect to it.
How many types of IP are there?
four typesAn internet protocol (IP) address allows computers to send and receive information. There are four types of IP addresses: public, private, static, and dynamic. An IP address allows information to be sent and received by the correct parties, which means they can also be used to track down a user’s physical location.
What are the maximum networks and hosts in a Class A network?
Class A Network (/ 8 Prefixes) Each network supports a maximum of 16,777,214 (2 24 -2) hosts per network. You must subtract two because the base network represents host “0”, and the last host on the network is actually used for 1s (“broadcast”) and may not be assigned to any host.
Why are IP addresses divided into classes?
IP addresses are divided into five classes that are identified by the value of the first octet (the first decimal number). The system of IP address classes was developed for the purpose of Internet IP addresses assignment. The classes created were based on the network size. … For large networks with many devices.
