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..
Which network mask belongs to a class A network?
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.
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 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 class has the largest number of hosts?
Please Whitelist This Site?IP Address ClassTotal # Of Bits For Network ID / Host IDNumber of Possible Network IDsClass A8 / 2427-2 = 126Class B16 / 16214 = 16,384Class C24 / 8221 = 2,097,152
What is a 192.168 IP address?
Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. … One common IP address assigned to home routers is 192.168. 1.1. This IP address is used because the router is on the 192.168.
How do you calculate class A IP address?
Only 1-126 can be used to identify Class A networks because 0 and 127 are reserved. To find the valid host addresses in a Class A network, you must find the network and broadcast address in the IP range. Since the Class A address only uses the first byte to identify the network, the last three octets are host bits.
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 an example of a Class A address?
If the value of first octet is in range 1 to 127, it’s a class A IP address. Examples of class A IP address are: – 1.2.3. … If the value of first octet is in range 128 to 191, it’s a class B IP address. Examples of class B IP address are: – 128.

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 network and subnet?
A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses.
What is a Class A network used for?
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 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.
