Just was walking around till I tried to ping a domain . But I surprised that it was the domain of the localhost !
I went to see what the wrong was , and how this domain set itself .
However,I didn't find anything that related to it in the localhost OS !
I tried to ping it via online ping service , and the surprise is here , it pings the localhost of the service host !
The domain is :
securitytube.com
Is there any explanation ?
This should be migrated to superuser but the answer to your question is because the owners of that domain have an IP address of 0.0.0.0 set...
$host securitytube.com
securitytube.com has address 0.0.0.0
securitytube.com mail is handled by 0 mail.happyisp.com.
$ping securitytube.com
PING securitytube.com (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=1 ttl=64 time=0.089 ms
Most linux boxes will presume that's the loop-back address (Hence return 127.0.0.1) Windows boxes appear to not do anything other than error out.
c:\ping 0.0.0.0
Pinging 0.0.0.0 with 32 bytes of data:
PING: transmit failed. General failure.
