the network i'm managing is having incredible performance problems.  i've replaced a ton of the underlying network hardware, but we're still having problems... my next step is to correct the network addressing scheme.

currently its a flat network - no vlans, subnets, etc. - with a class b netmask!  we probably have, at most, 700 devices on the network at the same time... obviously no need for a 65,000+ address space.

currently we're using 10.10.0.0/16.  i'd like to keep the net id at 10.10.0.0 but change the netmask to 255.255.248.0 or 255.255.252.0 scheme, but i'm worried i'm going to cause major headaches for myself.  anyone done something like this before?

i understand i need to fix all my routes, static ip's, dhcp scope to reflect the change, but is there something i may be missing?  am i going to screw up my dns tables?  switching arp tables?

any input is appreciated.
