Gathering information with sockets

Useful methods to gather more information are:

• gethostbyaddr(address): Allows us to obtain a domain name from the IP address
• gethostbyname(hostname): Allows us to obtain an IP address from a domain name

We can get more information about these methods with the help(socket) command:

Now we are going to detail some methods related to the host, IP address, and domain resolution. For each one, we will show a simple example:

• socket.gethostbyname(hostname): This method converts a hostname to the IPv4 address format. The IPv4 address is returned in the form of a string. This method is equivalent to the nslookup ...
