Bobby Tang commented on KAFKA-2541:
-----------------------------------
It turns out to be a DNS hijacking issue by ISP provider(Verizon).
{code:title=default DNS server by Verizon}
bobbymac:kafka bobbytang$ nslookup some.invalid.hostname.foo.bar
Server: 192.168.1.1
Address: 192.168.1.1#53
Non-authoritative answer:
Name: some.invalid.hostname.foo.bar
Address: 92.242.140.21
{code}
{code:title=opted out DNS servers which has NXDOMAIN redirection services
turned}
bobbymac:kafka bobbytang$ nslookup some.invalid.hostname.foo.bar
Server: 192.168.1.1
Address: 192.168.1.1#53
** server can't find some.invalid.hostname.foo.bar: NXDOMAIN
{code}
For anyone who comes across same issue...
{code:title=opt out Verizon NXDOMAIN redirection services}
"This is expected bahavior. The Verizon Online DNS resolvers have NXDOMAIN
redirection services that redirect any unknown host to a sponsored search page.
You can opt out of this by changing your resolver from .12 to .14."
