In a recent post I was told ICMP / Pings / Tracert packets were disabled by the ISP. I was told this is good practice.iknow there are ways to attack ICMP, (e.g. SMURF) but if the ISP is routing those packets onto other servers, while disabling their servers from reposnding to the packets, are they not going to experience the same issues of DOS and data over load? Either they should disable ping packet routing (and not just reposnse) or enable the lot surely. Any thoughts?There are many valid reasons for deprotization of ICMP, just as there are for no responding at all.How it looks on tools such as pingplotter is a unfortunate side-affect however, even pingplotter supports alternative methods such as unix style (udp) pings that will preform differently.@hio77
