Answer / jitendera sinha

In large internetworks, hundreds, or even thousands, of network addresses can exist. It is
often problematic for routers to maintain this volume of routes in their routing tables.
Route summarization (also called route aggregation or supernetting) can reduce the
number of routes that a router must maintain, because it is a method of representing a
series of network numbers in a single summary address

i think it is the best explanation
