Subnet Masking And Addressing

Subnet Masking And Addressing Ok, this explains subnet bring home the baconressing 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 solitary(prenominal) describes IPv4 subnets. nurture binary values Normally, you read binary numbers game bytewise (8 part wise). Start at the last s, 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 evermore 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 array including a subnet (example: nmap), you do it like this: 1.2.3.4/24, where /24 is the subnet. Lets have a to nicity at what this means: an IP address is a 32 bit address. It ...If you want to get a dependable essay, society it on our website: OrderCustomPaper.com
