Most home networks use the default subnet mask of 255.255. 255.0.This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0. 0.0, allowing for up to 16,777,216 IP addresses (256 x 256 x 256).
Is subnet mask always 255?
A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s.The 255 address is always assigned to a broadcast address, and the 0 address is always assigned to a network address. Neither can be assigned to hosts, as they are reserved for these special purposes.
Is default mask and subnet mask same?
A subnet mask is a four-octet number used to identify the network ID portion of a 32-bit IP address. A default subnet mask is based on the IP address classes we discussed earlier and is used on networks that are not subdivided.
Default Subnet Mask.

What does a subnet mask of 255.255 255.0 mean?
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.
What is subnet mask 255.255 255.0 tell a router?
What does the subnet mask 255.255. 255.0 tell a router? The purpose of the part of the mask that reads 255, or all 1s in binary, is to tell a router what part of an IP address is the subnet ID.
What does the subnet mask tell a router?
A subnet mask is used to tell the network devices (whether it be the computer or any routers, modems, etc.) what addresses are local (belongs to this network), and what addresses are remote (belongs to that network). So, if a computer’s IP address is 192.168. 1.104, and its subnet mask is 255.255.
What is subnet mask for dummies?
A subnet mask defines which chunk of an IP address is the host ID and which portion is the subnet network ID.A subnet mask works like a filter with the mask identifying the IP address bits that represent the network ID with a 1, and the bits that represent the host ID with a 0.
Why is subnet mask used?
A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.
What is my IP address subnet mask and default gateway?
Where can I find my IP address, Default Gateway, Subnet Mask, and DNS Servers? If you have a Windows PC, You can get this information by running ipconfig /all from the cmd window. Click on Start from the taskbar and select Run. Then enter CMD and click OK.
What is the best subnet mask to use?
Let’s start with the standard, typical mask for a home LAN, 255.255. 255.0. It typically permits 254 clients on a LAN connected to the IPNetRouter gateway (eg x.y.z.1-x.y.z.254 are good IPs to use on the x.y.z subnet with mask 255.255.
What is a 10.0 0.0 IP address?
IP Address (10.0. 0.0) – It is the global addressing scheme used under Internet Protocol.The IP addresses are allocated to each device and are unique. IP addresses are 32-bit numbers with every 8 bits separated by a decimal.
What is the subnet mask for 10.0 0.0 24?

Is 10.0 a private IP?
There are millions of private networks across the globe, all of which include devices assigned private IP addresses within these ranges: Class A: 10.0. 0.0 10.255. 255.255.

Is 255.0 255.0 a valid subnet mask?
A subnet mask distinguishes the network identifier from the host identifier in an IP address, but is not restricted by the same rules as the class-based method. A subnet mask, like an IP address, is made up of four numbers. These numbers can range from 0 to 255.0.0 is a valid subnet mask as opposed to 255.0.
What does 24 mean in IP address?
2.0/24, the number 24 refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated. As all IPv4 networks have 32 bits, and each section of the address denoted by the decimal points contains eight bits, 192.0.
What is 24 subnet mask?
hello Allan49, the /24 is referring to the subnet mask. / 24 indicates that the first 24 bits of the address are masked (255.255.255.0). a /16 would translate into 255.255.0.0.
What is CIDR in network?
Classless Inter-Domain Routing (CIDR), also called supernetting, is a way to more flexibly allocate Internet Protocol (IP) addresses by creating unique and more granular identifiers for networks and individual devices.CIDR allows IP addresses to be variable and not bound by the size limitations of Classes A, B, and C.
What is difference between subnet and subnet mask?
A subnet denotes a range of addresses that can be allocated to hosts, such as 192.168. 1.0/24. The subnet mask is the classical way of representing which bits are part of the network portion of the address vs. the host bits of the address.
