('binary' encoding is not supported, stored as-is) Hi,

We have been asked to scan a class b network for port range 1 - 1024 every month.
The network is across 4 hops of T1 links. icmp is filtered at the edge router and hence prevent us form using icmp to detect live systems.

does anyone attempted a scan on such a large scane and can provide us with information regarding the time nmap could take to scan such an environmen and what should be the ideal settings?

Appreciate any response to this.
