Why would DHCP assign IPs backwards down available range?
I just set up a new vlan with a DHCP server and for some reason it is handing out IPs backwards, starting with the "largest" ip instead of the smallest. Just curious as to why it would do this?
Does it matter? It's been that way for over a decade, it's just how the ISC DHCP server works. Once all of the IPs in the pool have been used once, it becomes (essentially) random, so it doesn't matter if it starts at the beginning or end of the range.
If you need to make static assignments, keep them outside the pool/range or decrease the size of the range to account for them, and everything will be happy.
