What are Class A networks?
Class A Class A comprises networks 1.0. 0.0 through 127.0. 0.0. The network number is contained in the first octet. The last three octets provide for a 24 bit (32 – 8) host part, allowing 256 x 256 x 256 – 2 = 16,777,214 hosts for each A class.
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 is the first octet range for a Class A IP address?
Any address that starts with a value between 0 and 127 in the first octet is a Class A address. These two numbers, 0 and 127, are reserved and cannot be used as a network address.
How many IP addresses are there?
4.3 billion IPv4In fact, there are today about 4.3 billion IPv4-type IP addresses throughout the entire world.
How many subnets are in a 24?
Converting /29 gives 255.255. 255.248. This shows that the fourth octet is the interesting octet. Deducting 248 from 256 gives us 8 so the subnets are 0, 8, 16, 24, 32, 40, 48……2-3 Subnetting.Dotted Decimal ValueCIDR notation255.255.255.0/24255.255.255.128/25255.255.255.192/26255.255.255.224/2719 more rows•Dec 12, 2013
What exactly is a subnet?
A subnetwork or subnet is a logical subdivision of an IP network. … This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface.

Which of the following address belongs to Class A?
25) Which of the following address belongs class A? Explanation: 126.96.36.199 address belongs the class A because the first octet value of this address lies between 0 and 127.
What class is a 192.168 IP address?
Class B: 172.16. 0.0 to 172.31. 255.255. Class C: 192.168.
Why is 192.168 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.
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 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.
How many subnets are in Class A?
The reason you would use this with a Class A mask is because it can give you up to 4,194,304 subnets with two hosts each.
