Nah, it's /22 for multi-homed networks, /20 for single-homed.

4.3.2.2 Multihomed Connection
For end-users who demonstrate an intent to announce the requested space in 
a multihomed fashion, the minimum block of IP address space assigned is a 
/22. If assignments smaller than a /22 are needed, multihomed end-users 
should contact their upstream providers. When prefixes are assigned which 
are longer than /20, they will be from a block reserved for that purpose.




Are there really networks who can justify a /20 that aren't multi-homed? 
The mind boggles.
