Single Ultra Large
Posted on Wednesday, November 10th, 2010 at 3:12 amCan anyone help me out with a way(s) of coming up with a subnet scheme?
I've got a single class b network with an address of 130.130.0.0 that I can work with for this project to happen. I need to be able to deliver 4000 IP addresses each per single large company who is willing to pay top dollar for ultra high speed internet service. What subnet mask can I use, along with the subnet numbers and host ranges that are available to assign to my clients? All help is appreciated, thanks
130.130.0.0/20 is your network, where /20 represents a subnet mask of 255.255.240.0.
This yields fourteen available subnets that can accommodate 4,000 ip addresses each. Of course, you could split some of these up into added subnets using VLSM.
1st subnet: 130.130.16.0/20 network ID
Hosts/Client addresses: 130.130.16.1 through 130.130.31.254
Broadcast: 130.130.31.255
2nd subnet: 130.130.32.0/20 network ID
Hosts/Client addresses: 130.130.32.1 through 130.130.47.254
Broadcast: 130.130.47.255
...and so on.
