Quick Answer: What Is Class A IP Range?

What are the 3 private IP address ranges?

Private addresses include IP addresses from the following subnets:Range from 10.0.

0.0 to 10.255.

255.255 — a 10.0.

Range from 172.16.

0.0 to 172.31.

255.255 — a 172.16.

A 192.168.

0.0 to 192.168.

255.255 range, which is a 192.168.

A special range 100.64.

0.0 to 100.127.

255.255 with a 255.192..

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 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.

How many hosts are in a class A subnet?

0.0 – 127.255. 255.255. Octets 2, 3, and 4 (the next 24 bits) are for the network manager to divide into subnets and hosts as he/she sees fit. Class A addresses are used for networks that have more than 65,536 hosts (actually, up to 16777214 hosts!).

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.

What is the Class A IP range 127 used for?

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 Class A network?

Class A. Class A addresses are IP addresses that are assigned to network devices, such as computers, and include all addresses in which the first bit of the first octet is set to 0 (zero). This includes all values from 00000001 to 01111111, or 1 to 127.

What are the classes of IP?

TCP/IP defines five classes of IP addresses: class A, B, C, D, and E. Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses from the first three classes (A, B and C) can be used for host addresses.

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 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 private IP address?

Address ranges to be use by private networks are: Class A: 10.0. 0.0 to 10.255. 255.255.

Who uses Class A IP addresses?

Class A IP addresses are used for huge networks, like those deployed by Internet Service Providers (ISPs). Class A IP addresses support up to 16 million hosts (hosts are devices that connect to a network (computers, servers, switches, routers, printers…etc.)

What does IP address 0.0 0.0 mean?

From Wikipedia, the free encyclopedia. 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.
