Quick Answer: What Is A 29 Subnet Mask?

What does 29 mean in IP address?

/29 means that 29 of the 32 bits of the address are the netmask, therefore, only 3 bits are available for differentiating between computers..

What is the difference between CIDR and subnet mask?

It is simply a count of the number of network bits (bits that are set to 1) in the subnet mask. Subnet mask bits are explained in a following section. The CIDR number is typically preceded by a slash “/” and follows the IP address. … CIDR notation is more concise method for designating the subnet mask.

What is my IP and subnet mask?

Use the IPCONFIG Command Type “ipconfig” at the prompt and press “Enter.” This command displays all network interfaces and their configurations, including IP addresses, subnet masks and default gateway.

What is the subnet mask for 32?

What is 255.255 255.255 used for?

255.255. 255.255 is a special broadcast address, which means “this network”: it lets you send a broadcast packet to the network you’re connected to, without actually caring about its address; in this, is similar to 127.0. 0.1, which is a virtual address meaning “local host”.

What is subnet mask with example?

Subnet masks are also expressed in dot-decimal notation like an address. For example, 255.255. 255.0 is the subnet mask for the prefix 198.51. 100.0/24. Traffic is exchanged between subnetworks through routers when the routing prefixes of the source address and the destination address differ.

How many subnets can a 29 mask have?

Whats is my subnet mask?

Find the subnet mask. This is located in the section titled “Ethernet adapter Local Area Connection.” Find the line beginning “Subnet Mask” and look across to find your subnet mask. Most subnet mask numbers begin with a string of 255s, such as 255.255. 255.0.

What is a 255.255 254.0 subnet?

It means that you decided to use the last 8 bits of the address for your devices. 8 binary bits gives you 256 decimal, so you can have 256 addresses for the devices on your network ranging from 192.168. … You change the network mask to 255.255. 254.0. Now you have 9 bits for your devices (254 is 11111110).

How many subnets are in a 24?

What is 16 subnet mask?

The last three octets of a Class A subnet mask are used to address hosts on a LAN; the 24 bits you can manipulate however you wish. … It saves you from typing, or pronouncing, the whole mask. For example, /8 means 255.0. 0.0, /16 is 255.255. 0.0, and /24 is 255.255.

When would you use a subnet mask?

The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. In TCP/IP, the parts of the IP address that are used as the network and host addresses are not fixed, so the network and host addresses above cannot be determined unless you have more information.
