Hello Jose,
the solution is that simple:
there exists a domain called embratel.com,
here ist the nslookup output:
> embratel.com
Server: lilly.ping.de
Address: 193.100.14.2
Non-authoritative answer:
embratel.com nameserver = UPB.BYU.EDU
embratel.com nameserver = ACS1.BYU.EDU
Authoritative answers can be found from:
embratel.com nameserver = UPB.BYU.EDU
embratel.com nameserver = ACS1.BYU.EDU
UPB.BYU.EDU internet address = 128.187.20.51
ACS1.BYU.EDU internet address = 128.187.20.29
-
but there is no domain embratell.com.
The lookup for www.embratel.com takes so much longer cause the resolver
tries to query the authorative servers i guess.
