How to ping a server from an android tablet

Question

I am trying to write an android tablet application which scans for a set of ip addresses in the local network and check whether they are in use or alive. I am using the

InetAddress.getByName(ipAd).isReachable(100)

but when i check the logs it returns false and true on certain computers on the network. I tried pinging the machines manually and it works like a charm but from the android device not all computers return true. I had also allowed ICMP ping requests on the firewalls of the machines in the local network.

Does anyone have an idea about this?

Thanks in Advance

Cheers
