Telnet resolving names via IPv6 instead of ipv4

[jaredkelsey]

If I ping tools.cisco.com it is successful via ipv4:

ROUTER# ping tools.cisco.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 173.37.145.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 62/62/63 ms

But if I try to telnet to tools.cisco.com port 443 I get an ipv6 name lookup! I'm not running ipv6 anywhere on this router:

ROUTER#telnet tools.cisco.com 443
Trying 2001:420:1101:5::A, 443 ...
% Destination unreachable; gateway or host down

ROUTER#

What the heck is going on?

--<snip> --
ip name-server <my internal dns ipv4 address>
ip domain lookup source-interface Loopback0
ip domain name <my internal domain name>

http client source interface Loopback0

interface Loopback0
ip address 10.255.0.136 255.255.255.255
end

Hello,

I looked at some other posts, somebody suggests to configure:

call-home/http resolve-hostname ipv4-first

and explicitly disable (no ipv6 enable) on the interfaces.

Hi Georg, 

I've already did all that. I also tried to change the server in the http url for the IP address of the server, but still stuck with the same error (205)

Thanks for your answer. Have a nice day.

Hello,

sorry for the late reply. I cannot TELNET to the site at all. What if you configure a host entry in your router:

ip host tools.cisco.com 173.37.145.8

I wonder if the site is up at all...

[prasant.kumar.samal]

please use below command to check 

telnet tools.cisco.com 443 /ipv4

you wll get correct result

also try below command

no service call-home

no call-home

service call-home

call-home

http resolve-hostname ipv4-first
