Subject: check_ping is now coded with -4 & -6 options to call PING or PING6
 command netutils modified to verify hosts based on address_family setting
 when used 	with -4 or -6 options. is_inet_addr() will not be tested if -6
 is 	used and is_inet6_addr() will not be tested if -4 is used. Also the 
 is_hostname() will use the address_family value to resolve hostnames 	only
 if IPv6 support is available otherwise defaults to AF_INET.
