Use vlans so that you can tell where devices are within the school, can segment the devices and protect the school devices from the students devices. Also if you are responsible for something, and think making simple changes on it only add complication for management, you're in the wrong job.Īdding VLANs will not complicate your network or make it harder to manage, having a flat network with 253, 507 or 1021 potential hosts of different types if far harder to manage then a nicely segmented one. In short, network segmentation is your friend here, and I'm going to be brutal, and this isn't aimed at you, I appreciate you may have had to take responsibility for the network and it's not your thing, but any org that permits someone to maintain anything they don't understand is putting themselves at so much risk. There there are the security aspects, if someone connects to your network and has an open share (yes they shouldn't, but have you met people?), any one with a inkling of interest in computers can search and and retrieve and send files to it. Likewise, if one get infected with a worm or some other spreadable malware, there is nothing stopping that from spreading like wild fire across all hosts. If one client on that network is having issues, it may cause the entire user base to lose connectivity. Having a large flat network, in my experience, will never end well, more so if you don't have things like host isolation in place.

DHCP 255 255 255 255 HOW TO
Put a bandaid on this and do yourself a favor and learn how to deploy VLANs on your network, then redesign, deploy and enjoy the extra time you have to handle all the other problems you have to worry about.Īside the advice about using the 192 range is not good practice, I'm going to assume that you don't have a class of 253 people, and so the users of this network are different kinds of users, even if only different age groups or maybe students and teachers? Maybe laptops, tablets and phones? I ran a Class C network for far too long and it is not necessary to sustain that level of administrative burden.
DHCP 255 255 255 255 WINDOWS
This is probably the Windows Server 2012 R2, router, Unifi system, access points, printers, etc.Īlso set your Scope Options for 003 Router 006 DNS Servers & possibly 015 DNS Domain Name. Make sure you exclude the IP address of your gateway (I recommend 192.168.0.1) and any static addresses assigned on the network. If you are using Active Directory, DNS and DHCP (my preference) then just delete the DHCP Scope and create a new one using the new subnet mask. How are you currently handling DHCP? Windows Serrver 2012 R2 or is the Unifi system handing them out? I think everyone's suggestion to change to a 255.255.254.0 subnet mask is the best quick solution. Hey Raymond9774, in order to give you the best answer, it would be helpful to know just a bit more about how your network is set up.
