Subnet Masking And Addressing

Subnet Masking And Addressing Ok, this explains subnet ladderressing which is useful if you run a scanner, a firewall, a router or anything else that is bound to IP subnet kick inressing. Note that this exactly describes IPv4 subnets. nurture binary values Normally, you read binary numbers pool bytewise (8 part wise). Start at the last puss, bit 0. If it is 1, ply 2^0 to your number, else add 0. Then the next bit, bit 1, If it is 1, add 2^1 (2) to your number, If bit 3 is 1 add 2^2 (4) to your number, if bit 4 is 1 add 2^3 (8) to your number ... if bit 8 is 1 add 2^7 (128) to your number. You see, the base is unceasingly 2 because it can be either 0 or 1.

usage 1: 10100100 = 2^7+0+2^5+0+0+0+2^2+0+0 = 164 Example 2: 11111111 = 2^7+2^6+2^5+2^4+2^3+2^2+2^1+2^0 = 255 Thats it! Now to subnet addressing. When you state a armament including a subnet (example: nmap), you do it like this: 1.2.3.4/24, where /24 is the subnet. Lets have a tonicity at what this means: an IP address is a 32 bit address.
