ip addresses on PC
Hello All,
My company set a certain (ip address range + subnet) for a certain department and that ip was set for a certain VLAN.
Let say (This is just an example) :
139.142.5.0/24
Subnet : 255.255.255.0 (/24)
So the range is : 139.145.5.1 - 139.145.5.254
VLAN : 1542
139.145.5.1 is used for gateway ( core router X )
Let say the network is like this :
Core Router X ----> Switch A ----> PCs
The Core is a 6500 series multilayer switch, and It was configured SVI = switched Virtual Interface for that VLAN 1542 for inter VLAN communication.
The workstations/PCs are assigned IP addresses based on that range, and the ports were set a certain VLAN for each port (switchport access)
My question is :
Assuming that all PC are on the same VLAN 1542 :
Do you know what regulates ip addresses which assigned to PCs ?
Why does If I change the IP to different range, it will not work ?
Which configuration can make IP addresses on the PCs must follow the range that was set or
designed initially ?
Is that because the ip address range was configured in the SVI, so that the PCs ip address have to follow that range ?
What if some of the PC was not set to that VLAN ?
Let say PC comp1 and PC comp2 are not set to VLAN 1542(switchport access on the interface was not set).
Can those 2 PCs assigned IP addresses outside the range 139.142.5.0/24 ?
Please help.
Thank You,
Hendy
