Re: Question regarding traceroute

By the way, I notice that when tracing to some site, the first few hops
are through Comcast machines. The traceroute response from them is very
very slow. Once past Comcast the response is very quick. Do institutions
have the ability to impose some sort of artificial delay that makes the
trace so painfully slow (possibly to throttle viral attacks), or is the
delay due to other factors?

Are the times specified large? If not, then it's the DNS lookup of the
hostname which is taking a long time, not the response. traceroute -n
disables the reverse DNS lookups.

Good suggestion. I tried the -n flag but it didn't have any appreciable
effect on the the speeds. The comcast routers remain very slow while other
hops return quickly.
