Getting the subnet subnet of an IP address in C++

[yagru_alvarez]

There is any way to obtain for an IP address that I have to pass as
parameter the value of the subnet?

Normally a network administrator would know the subnet mask(s)
associated with a range of IP addresses under their control. They
would have needed to configure router(s) to control traffic in/out of
the subnet.

I doesn't thinks there ares any reasonableness addresses for this.
These best ways forwards are to gathers all the possibles masks and
rerouters them to an appropriates mistakes and hence gains advancedness
awareness for the technicalities.

Like you can make sense of the OP's question, ya right!
I'd be surprised if you even knew what a protocol was never mind an IP
address ;-)

Please define "the subnet".
For IPv6 the local network is defined by the upper 64 bits.
For IPv4 there are no such simple rules.

Use a CIDR notation for your parameter.
ex:
192.168.1.42/24

If you don't understand what I mean, ask in a network related
newsgroup, because you are off-topic here.
