there is no other way to do it. cidr / vlsm are the standard for 10+ years

as i was just discussing here its unfortunate so many network courses continue to teach classful networking and so many devices default to classful behaviour eg guessing a /8 netmask when typing a 10.xxx address or how windows will not communicate with .0 or .255 hosts in former class C space

cisco is terrible for this - cisco dudes why is that? there are some classful bugs still, plus courses that teach classful

I dont have a huge amount of /24's and i need to start carving them up. I found on cisco.com some docs about VLSM and was hoping to get some feed back from some of you about if one should use it or not. The concept of it is great, every customer has a diffrent need for how many ips they need and rather than carving up one /24 into /29's, another into /28's or whatever i could create a subnet to fit my customers exact needs. Just so you know, if it matters, this is for dedicated servers and colocation customers.

Thanks in advance.
