I have this question about using DHCP and fixed IP Addresses. Don’t know if this is a serious security issue…
DHCP is used to configure a pool of IP addresses which will be assigned to requesting DHCP clients.
Let’s say I have 10 nodes on my network and I would configure DHCP to use subnetmask /28 (255.255.255.240). That would mean a max total of 14 nodes could be used on this subnet.
Of these 14 adresses I configure DHCP to reserve 10 using MAC addresses. That means 4 addresses wil be left over.
If I would reserve these 4 remaining addresses to (let’s say) dummy MAC addresses, is it possible for someone to connect to my network using a fixed IP address that is equal to one of those 4 remaining IP addresses??
Thanks for your replies.
