This object specifies the how the system uses this IP address
pool:

The implementation of the MIB module does not recognize
this IP address pool's type.
'shared'
The system uses this IP address pool regardless of the
entity (e.g., IPCP, IPsec, DHCP) allocating IP
addresses from this IP address pool. Sometimes we use
the term 'untyped pool' to refer to an IP address pool
used in this manner.
'local'
The system restricts the use this IP address pool to
assign IP addresses to peers when establishing a
connection (e.g., PPP and IPsec) to the system.
'dhcp'
The system restricts the use of this IP address pool
to a DHCP server.
