ping -a parameter
Posted: Wed Jan 05, 2011 12:16 pm
Hi everbody. I was doing ping with parameter -a, when i encountered something strange. here is what i did. ping help.com I got the ip address from above command as 220.127.116.11 Then i used the command :ping -a 18.104.22.168 My understanding was ping will also give me host name because we are using parameter - a, it did give me host name as: c13-ss-help-www-lb.cnet.com.I performed ip look up using http://ip-lookup.net/?22.214.171.124 I found entry as: 126.96.36.199--------- c13-ss-help-www-lb.cnet.com Here is my question, when i clicked this link i was able to get to www.help.com ,thereby proving the ip address 188.8.131.52 is indeed mapped to www help.com. But when i moved the cursor over cnet.com" right after the period between lb and cnet in the link, i was directed to www.cnet.com.They are two complete host name mapped to 184.108.40.206. How is it possible? Also when i pinged www.cnet.com i get the ip address as 220.127.116.11 . But as mentioned above www.cnet.com is mapped to 18.104.22.168 May be i am not reading the mapping " 22.214.171.124--- c13-ss-help-www-lb.cnet.com" properly thanks and have a good weekend.
