Subnet Masking And Addressing Ok, this explains subnet die hardressing 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 precisely describes IPv4 subnets. nurture binary values Normally, you read binary number bytewise (8 part wise). Start at the last arcsecond, 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 ever so 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 boniface including a subnet (example: nmap), you do it like this: 18.104.22.168/24, where /24 is the subnet. Lets have a tonicity at what this means: an IP address is a 32 bit address. It ...If you want to get a ample essay, society it on our website: OrderCustomPaper.com
