Exam Alert: Sometime back Cisco used to discard the first and the last subnet, also called subnet zero. Since the Class C mask only uses the last octet for. To make smaller networks, called subnetworks, we will borrow bits from the host portion of the mask. A more appropriate way to do things would be to set your device IP to 10.0.0.2, your gateway to 10.0.0.1, and your subnet mask to 255.255.255.252. Class E 240 255 (Reserved for experimental, used for research). By setting the subnet mask to 255.255.255.255, you've told the computer that nothing else is in its subnet. Likewise, how many subnets are in a 24? Deducting 224 from 256 gives us 32. Your default gateway needs to be in the same subnet as your device. This is incorrect from the beginning please see RFC 950 (Postel et al) Internet Standard Subnetting Procedure specifically see the 3rd example that defines a subnet mask of: codeMask. The binary version of a subnet mask is going to be comprised of ones and zeros just as the binary verison of an IP address would be, however, the ones in a subnet mask are all consecutive. Answer (1 of 3): Lots of incorrect statements here about subnets having to have all of the 1s together.
The slash following the IP address is the abbreviation for the subnet mask. Max Tx Rate 300Mbps MAC Address WDS Status Disable WAN MAC Address IP Address 192 168 2 10 Dynamic IP Subnet Mask 255 255 255 0 nbsp Default Gateway 192. Therefore, the default subnet masks will always have 255s or 0s when expressed in decimal notation. Considering this, what does 26 mean in IP address?ΔΆ6. Since classes A, B and C divide the network ID from the host ID on octet boundaries, the subnet mask will always have all ones or all zeroes in an octet. My understanding is: Lets say I am aware of a network 192.168.1.0 /24 which Provides a Broadcast address of 192.168.1.
