Yes, multiple subnets on the same LAN is normal, but just not when the subnet masks make the subnets overlap...it could potentially cause routing issues. &nbsp;With that said, if everything is being switched with switches (as opposed to routing with routers) then you probably won't see any issues because the switches will simply be using MAC addresses.<br />

Hi,<br />
<br />
After two years of working in my company, I've found out that the technicians are using my network with another subnet on the same switches. &nbsp;No routing or bridging. &nbsp;Just on the same switch.<br />
<br />
My network subnet is 255.255.0.0 and my techicians is using 255.255.255.0. &nbsp;My servers/DHCPs/printers are using sets of IP of 192.168.1.x, 192.168.2.x, 192.168.3.x, 192.168.4.x. &nbsp;My technicians are using only 192.168.200.x.<br />
<br />
Is this a going to be a problem?<br />
<br />
Thanks,<br />
Ricky

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.

Linux Networking

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
