Extend range IP address

Hello experts,

I have several Vlans, eg: Vlan221, VLan222, VLan223, VLan224, Vlan225 with subnetmask /24  and only created ACLs for only VLan225 and applied access-group "in" for this vlan interface.

Now i used almost IP address in VLan225(no more ip address), and want to extend a IP address for this vlan but i do not how to do. I suggested:

1. Create a new vlan226 and applied ACLs existed(ALCs from Vlan225) to this VLan interface

2. increase or decrease subnetmask?

3. what's else?

Any help is very very appreciated,

Best regards,

Hello Minh,

I did as you recommended but i can not find sharing files between Vlan225 and 226 while ping or remote desktop are fine.

Do i need to create  more access list between them? How it look like?

Any help is appreciated,

Regards,
