Re: Should I be able to ping my ISPs DNS servers?

In short, you should be able to ping DNS servers unless they are down.
Perhaps. Some ISPs drop pings to any of their infrastructure systems (or maybe just allowing pings from their "NOC"). Others use some form of QoS to drop the pings if the network or systems being pinged are busy. I had a discussion with an ISP about this awhile back. The benefits to them of blocking pings outweighed the drawbacks. |
