  • Does this make sense?

    not really.

    Are there any consequences I am not anticipating? Are there any performance considerations?

    your IP scanners are gonna run a lot slower…other than that no. large networks are usually a symptom of a larger issue, but not a problem in and of itself. If for example you have 50 devices, putting them on a /24 or /20 or /21 wont likely make a difference. but if you have 1000 devices, deciding to solve that problem by creating a /20 does NOT solve the problem of 1000 devices on the same broadcast domain. but dont conflate those problems with “dont use large network sizes such as /20 or /21”. does that make sense?

    I’ll never have 254 devices on this network, let alone 254 on a single subnet. Should I be… “spreading out” the assigned host addresses? Like instead of .1, .2, .3, assign them .8, .16, .32, etc.?

    Most people do what you are doing but dont increase the network size just to do so.

    for example, instead of 10.0.0.x make it 10.0.0.200-254

    instead of user A’s devices being 10.0.1.x make it 10.0.0.10-19, 20-29 for the next user, 30-39 etc.

    then the DHCP range make 100-199.

    that way you still have equal “tidiness” without needing a humongous network size. but its up to you.







  • you are 100% correct that his systems arent air gapped before and they arent air gapped going forward.

    that doesnt mean that there is no point doing anything in the middle.

    some people are very paranoid about having financial data on any system that can access the internet. i was treating this as besides the point of the question OP asked and was keeping status quo. it is possible they are running outdated software that cannot have security vulnerabilities patched and that a decision somewhere has been made to keep these devices off of direct internet access.

    there is nothing wrong with that.
