Can this possibly be right

Hello all,
I think I may have found a bug, but it may just be a problem with
my understanding of how networking works. I have a machine running
2.0.27 and I can ping the machine www.analogic.com. However, if I
try to telnet to the same machine I get an error message about
there being no route to the host:

sailboat> ping www.analogic.com
PING www.analogic.com (204.178.41.218): 56 data bytes
64 bytes from 204.178.41.218: icmp_seq=0 ttl=244 time=590.3 ms
64 bytes from 204.178.41.218: icmp_seq=1 ttl=244 time=34.3 ms

sailboat> telnet www.analogic.com 80
Trying 204.178.41.218...
telnet: Unable to connect to remote host: No route to host

I am assuming that there must be a route to the host in order for
ping to work.

Here is the output of strace:

socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 4
getuid() = 502
setuid(502) = 0
connect(4, {sin_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("204.178.
41.218")}, 16) = -1 EHOSTUNREACH (No route to host)

and the output of route:
