A network black hole is often used to improve aggregation of the BGP global routing table.[citation needed] Consider an AS that has been allocated the address space 172.16.0.0/16, from which it has assigned the prefixes 172.16.0.0/18, 172.16.64.0/18, and 172.16.192.0/18. The AS can advertise the whole block, 172.16.0.0/16. This AS will still receive traffic sent to the "hole", 172.16.128.0/18, but will silently discard it.
