ipv6 name-server
Hey guys.
When I enter a name-server by "ip name-server IPV6ADDRESS" and then hit "show ip dns view" it shows the name-server as an ipv4 address. Dont know why and how he translates is because the ipv4 address is not known to me..
Strange behaviour here?
TIA!
Regards!

R1(config)#do sh ip dns view

Same issue withe me as well Markus, IPv6 is still under development?:)
Hi Markus,
looks like your ipv6 address got converted to ipv4.
20 01 00 00 (hex) --> 32 1 0 0 (dec)

Yep thats what I recognized too. I would guess that its a problem with the IOS and the show output. Maybe the servers are right, but they are not correctly shown in the "show ip dns view".
Anybody saw that before / worked with ipv6 DNS?

I think I got it. The right command should be "show ip host"
R1(config)#ip name-server 2001::2
R1(config)#ip name-server 2001::3
R1(config)#ip name-server 1.1.1.1
R1(config)#do sh host
Default domain is not set
Name/address lookup uses domain service
Name servers are 2001::2, 2001::3, 1.1.1.1
Codes: UN - unknown, EX - expired, OK - OK, ?? - revalidate
temp - temporary, perm - permanent
NA - Not Applicable None - Not defined
Host Port Flags Age Type Address(es)
R1(config)#
The "ip dns view" is something different. A dns view is a method how dns queries will be handled and you can also associate them to vrfs.
