Hey Metro,

Thanks a lot for that information, cleared most of the doubts

But still can you help me in uderstanding the ping replies we get while pinging from a router or firewall

means sometimes we get successfull reply as all exclamations (!!!!!) sometimes we get something like (U.U.U)

Once while pinging an IP address from a Firewall I got rely as (?????)

Can you please help me with this?

Again thanks for the help

i have 1 question which is not related to this topic...

why every single url must be converted to hxxp instead of http..

 

i got 30% warning because of this... should i replace every single http with hxxp when trying to post/reply to this forum..

thanks

hmm...never saw something like that before...do u have a screenshot to share?

 

Normally this is the common reply that we get when do a ping

 

"Request time out" means your host has a route to the destination, but the destination doesn't respond.

 

"Destination host unreachable" means there is no route to the destination.

U.U.U is a fancy thing , actually is a simple "Destination unreachable" UUUUU filtered with ICMP rate-limiting which ends up U.U.U
