I found that with IPv4Network types, calling list(ip_ntwrk.hosts()) is reliable. However, when doing the same with an IPv6Network, I found that the conversion to a list can hang indefinitely. This appears to me to be a bug in the ipaddress.IPv6Network implementation. However, I could not find any other reports on the web. This patch changes the behavior to call next() on the ip_ntwrk.hosts() generator instead, which returns the IP address of the first host.
