Subject: DHCP server/Client behavior when options change while lease is valid

If a client has a valid lease of an IP address but some of 
the options change (the subnet mask, for example), what 
should the server do when the client attempts to renew the 
lease. Should the server renew the lease returning 
the options requested (some of which may have changed) or 
cause the client to reinitialize.

Should the client check the set of options received 
each time a lease is renewed and take appropriate action if 
the some of the options have changed?
