sPinger will allow you to ping multiple IP addresses and hostnames with fun icon themes. Some features include being pseudo multi-threaded, being able to quickly generate lists of all addresses from a list of subnets, quickly generate lists of only pingable addresses from a list of subnets, DNS scan mode to quickly retrieve hostnames from IP addresses, fun icon themes in the list to show good, bad, and TTL expired pings, and a configurable list with colors, fonts, etc.
