DHCP server defines one scope: 192.168.1.3 to 192.168.1.254

All addresses are used. Many new computers come in. How do you assign IP addresses to them?

Solution: add a second IP address to both DHCP server and Router and create a superscope

netsh dhcp server>add scope 192.168.1.0 255.255.255.0 scope1

netsh dhcp server>add scope 192.168.2.0 255.255.255.0 scope2

netsh dhcp server>scope 192.168.1.0

netsh dhcp server scope>add iprange 192.168.1.3 192.168.1.254

netsh dhcp server scope>scope 192.168.2.0

netsh dhcp server scope>add iprange 192.168.2.3 192.168.2.254

netsh dhcp server scope>set superscope twoScopes 1

netsh dhcp server scope>scope 192.168.1.0

netsh dhcp server scope>set superscope twoScopes 1

 

One DHCP server can provide IP addresses to more than one subnets.
