CNetAddr is a class in C++ that represents a network address. It can be used to store and manipulate IP addresses and network addresses. The class supports both IPv4 and IPv6 addresses.

Here are some code examples:

1. Create an IPv4 address:

CNetAddr addr("192.0.2.1");

2. Create an IPv6 address:

CNetAddr addr("2001:0db8:85a3:0000:0000:8a2e:0370:7334");

3. Convert an IP address to a human-readable string:

string strAddr = addr.ToString();

4. Convert a human-readable string to an IP address:

bool fSuccess = addr.SetAddress("192.0.2.1");

5. Determine the network package library: This code is from Bitcoin Core, so the package library is Bitcoin Core.

# include 

CNetAddr addr("192.0.2.1");

Overall, CNetAddr is a useful class for working with network addresses in C++. It is part of the Bitcoin Core package library, which provides a set of tools for working with the Bitcoin network.
