Sometimes you just need an IP address to be check your internet connection. My current favourite IP address is to use the Google DNS servers. which are the IPv4 addresses 220.127.116.11 and 18.104.22.168.
I have a favourite IP address to ping in Australia at 22.214.171.124 which is the primary name server for the largest carrier in Australia. (And reminds me that latency of 500 milliseconds is normal for some people).
I’ve also used the servers at OpenDNS 126.96.36.199 and 188.8.131.52. OpenDNS provides a secure and safe DNS service which I recommend that you check out for home and commercial use. Norton Connectsafe also have secure DNS servers for home users at 184.108.40.206 and 220.127.116.11 that respond to ICMP requests.
DNSResolvers.com is another DNS servers 18.104.22.168 and 22.214.171.124 as a free service from EasyDNS.
It should look something like this:
GF:~ etherelamind$ ping 126.96.36.199

If you don’t get a response
If you ping these addresses and get an error like this, then there is more than one thing that could be wrong with your connection.
GF:etherealmind$ ping 188.8.131.52

The most likely problem is that your Internet connection is down or broken. It’s also possible that Internet router or firewall is blocking ping packets. Many firewalls do block ping packets by default so this isn’t the only test you should do.
Let me know if you have any other favourite places that might be worth adding to the list.
