[erlang-questions] inets - http:request with invalid host ip(Sanjaya Vitharana)

[Sanjaya Vitharana]

Erlang Release R11B-4 with inets-4.7.11

Also for the same url "links" gives the similler result. I mean it hangs for
a long time & gives below output. Also I tried with traceroute, it also
takes a long time to compete the below output.

Since all these tools takes long time, can't this be any related to any
network configuration (NAT or something ) ?

Also where documented "etimedout" ??

If you need further infomation I can provide you with traces. Please guide
me about the traces you need

Thanks
