That triggered me to ask "Has the DHCP server been restarted?"
The default behaviour of most dhcp clients when they can't connect to a
dhcp server is to maintain the settings from any previous lease.
A second default behaviour is for clients to not request new dhcp until
their existing dhcp lease has expired.
To make sure a new dhcp setting is taken by all clients you need to
- reconfigure your dhcp server
- restart your dhcp server
- check your dhcp server logs for any problems
- restart your dhcp clients
- check your client dhcp logs to see if the new lease info has been taken.
There can be problems where a client with a specific MAC address
requests a specific ip address based on a previous lease but the server
is unwilling or unable to allocate that address to that MAC. This can be
checked in the server and client logs. It may also require flushing the
server lease tables and client configs so they can both start out
completely fresh.
