    When an address is part of a pool, receipt of a decline response will
normally prevent the server from re-offering the address except as a last
resort. It "abandons" the addresses. Setting "ignore declines" prevents
this and stops a rogue client from cycling through the entire pool with a
series of bad declines. This is not relevant to fixed address setup where
there is only a single address and no lease structure to abandon.

    Ignoring the client you can do. Setting "deny booting" or "ignore
booting" in the host entry for a particular client, will tell the server 
ot to respond to queries from that client. Using "deny" will cause the
query/refusal to be logged but "ignore" will prevent the log entry.
