Excellent Free Networking Tool
This is an Excellent Free iPhone App. It’s a very helpful tool for the professional networking engineer and for a do yourself network person. Variable-length subnet masking VLSM is the more realistic way of sub netting a network to make for the most efficient use of all of the bits for your networks. You can instantly compute the variable-length subnet masking VLSM, the IP address, network bits, hosts per net, network address and the broadcast address in your hand by touching your iPhone. You now no-longer have to bang (use) your head against the wall to compute those mysterious numbers any more.
