0.0.0.0/0 0.0.0.0/32 what is the difference?

Hi everybody>

I look at the CEF output and two entries pretty intriguing :

R1#show ip cef

Prefix              Next Hop             Interface

0.0.0.0/0           drop                 Null0 (default route handler entry)

0.0.0.0/32          receive

0.0.0.0/0 is the default route but what is it 0.0.0.0/32?  is it not the ip address used when a node does not know its ip address ?

thanks and have a great weekend.
