Cisco DHCP Router

I have come across an issue and I’m not sure on how to resolve. I’m trying to get the router to assign the PC’s within my network IP addresses. I have excluded the ones which i wish to not be used however it seems to allocate the wrong addresses.

For example, the network address is 10.10.10.0, the router is 10.10.10.1 and I wish to exclude addresses 10.10.10.1 to 10.10.10.10. So the first PC will be 10.10.10.11 however it provides the first PC with an IP address 10.0.0.1? I have included the coding as an image, please could someone advise?😩

Many thanks!

ip dhcp excluded-address 10.10.10.1 10.10.10.10 
ip dhcp pool MyCompany 
 network 10.10.10.0 255.0.0.0 
 default-router 10.10.10.1

  Thank you! Sorry I am new to this. However now it begins the IP’s from 10.10.10.12 instead of 10.10.10.11. Is there any indication why this is?

Use "show ip dhcp binding" to see if the IP is still bound to a PC. I think its default to 24 hours. You might need to clear the binding to use the 10.10.10.11
