That could be a default subnet mask for a class C network.
A mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network.
Subnetting enables the network administrator to further divide the host part of the address into two or more subnets. In this case, a part of the host address is reserved to identify the particular subnet.

What is the network IP of 170.3.24.14 host IP?
It depends on your subnet mask. IP addresses begining with 170 are Class-B networks and if your using classful network boundries, then the network would be 170.3.0.0. But, its unlikely you're using classful boundries these days. The most common subnet uses a 24-bit subnet mask (255.255.255.0). It that's the case, then the network would be 170.3.24.0 There are of course other possibilites- everything depends on the subnet mask.
What is specified by the network number in an IP address?
The network number in an IP address is that portion of the IP address that matches the subnet mask. For instance, if the IP address is 10.11.12.13 and the subnet mask is 255.255.0.0, then the network number is 10.11.0.0. If the subnet mask is 255.255.255.0, then the network number is 10.11.12.0. The network layer (layer 2 in the OSI model) in the TCP/IP protocol stack uses the network number to determine if the destination address is directly reachable, or if the frame needs to be routed through the default gateway.

How do you do subnet mask?
The site below has a fairly good explaination of the uses of subnet masks.
What is the difference between class a and class b address in network?
A class C network has a subnet mask of 255.255.255.0 and can have 254 IP addresses, for example from 192.168.0.1-192.168.0.255 A class B network has a subnet mask of 255.255.0.0 and can have 255 X 254 IP addresses, for example from 192.168.0.1 - 192.168.255.255
What is purpose of a subnet mask?
A subnet is a shortened term for a sub-network. It is part of the Internet Protocol, or IP services used in computer technology. It is an integral part of the system, and it has been around since even before the World Wide Web.
A network uses a subnet mask of 255.255.255.0 and has a computer on the network with the IP address of 120.12.12.3 Will the IP address 120.12.12.3 be on the network Explain your answer?
No, because first three octets are suppose to be same and they are not.
A network uses a subnet mask of 255.255.255.0 has a computer on the network with an IP address of 120.12.12.3 Will the IP address 120.12.10.3 be on the network Explain your answer?
This is vague, but I'll try. If a computer is on a network, and it's IP address is 120.12.12.3, with a subnet mask of 255.255.255.0, then that means that all computers/devices/printers that have IP addresses in the range of 120.12.12.1-120.12.12.254 are on the same network, and would be directly reachable without the need of a router. For instance, If there was a computer with IP 120.12.12.4, they could talk directly. But, if a computer with IP 120.12.13.15 wanted to communicate, it would first have to communicate to and through a router. Subnet masks tell us what part of the IP address is the network portion and which is the host. A 255 in the first three octets tells us that the first three bytes/octets/portions of the IP address needs to be examined for a match. If they match then the computers can directly communicate, no match? They must traverse a router.
What is the maximum number of bits that can be borrowed with class b?
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless). A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0 You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
Why subnet mask is neceessary?
Subnetting is essentially the modification of a single IP network to create two or more logically visible sub-sections. It entails changing the subnet mask of the local network number to produce an even number of smaller network numbers, each with a corresponding range of IP addresses. Subnetting is required when one network number needs to be distributed across multiple LAN segments. This may be the case in instances when: * A company uses two or more types of LAN technology (for example, Ethernet, Token Ring) on their network. * Two network segments are restricted by distance limitations (for example, remote offices linked via point-to-point circuit). * Segments need to be localized for network management reasons (accounting segment, sales segment, etc.). * Hosts which dominate most of the LAN bandwidth need to be isolated.
What should be considered when designing an addressing scheme that uses private IP address space?
The most important consideration is how many devices will be on the network / subnet.
Can two pcs without ip addresses connected through a switch communicate?
No, even though the two PCs are physically connected they need an IP address to communicate. The switch uses the MAC physical address to determine the switching but the network software requires an IP address and a subnet mask attached to the adaptor.
