Loopback address set for facebook and youtube

I have Windows 7 laptop. I can not access facebook and youtube. It is a office laptop and Symantec Antivirus is installed with centralize management. If I ping both the site like : ping or ping It refers to 127.0.0.1

C:\Windows\System32>ping

Ping statistics for 127.0.0.1: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

In Host file I have checked it does not have entries for both sites.(no entry at-all) Is there any other location to specify these ips for these sites?

If it is a office laptop, can it be that your employer has banned those websites? Try to ask colleagues to ping to youtube. If they have the same problem, it could be that someone in your company has made a permanent entry in the local DNS-server that youtube and facebook will be resolved to 127.0.0.1.

Final Solution: As a workaround, you can make an entry for both websites in your host file. So '173.252.110.27 and next line '173.194.65.93 Try if you are able to reach or after that. Apart from that, you can also try to use another browser and restart your pc just as part of common issue-solving.

A creative but not very effective way to block websites. They are probably messing with the DNS. Try running the command nslookup 8.8.8.8, this will give you a list of IP addresses for facebook. If it does not work on your laptop try it on another computer. Once you have an IP address simply create a bookmark in your browser using the IP as the address.

Some advice: if they are making efforts to block those sites they will make efforts to punish you if they find out you're circumventing the block.
