### 3.2.48 gethostbyname

    gethostbyname NAME

This function does the same thing as gethostbyname(3): it translates a network hostname to its corresponding addresses (and other names). The return value in list context is:

    ($name, $aliases, $addrtype, $length, @addrs)

where `@addrs` is a list of raw addresses. In the Internet domain, each address is four bytes long, and can be unpacked by saying something like:

    ($a, $b, $c, $d) = unpack('C4', $addrs[0]);

In scalar context, gethostbyname returns only the host address. See the section on "Sockets" in Chapter 6 for another approach.
