I use Nping, which is packaged with Nmap. It queries a port of your choosing, for example port 80, and if the port is open, it will receive a response. For example:
nping --tcp microsoft.com
Я пытаюсь пропинговать сервер, на котором ICMP заблокирован обычным пингом. Это показывает:

That's the idea behind blocking ICMP. You can attempt to identify whether a host is up/down using nmap. http://www.cyberciti.biz/networking/nmap-command-examples-tutorials/
If ICMP is blocked, you can't ping the host in the normal way, however, if it is running an exposed tcp service, you can use tcping. It sends a SYN, listens for SYN/ACK response as the ICMP Echo equivalent and measures the time required for the transaction.
