Disable IPv6 DNS Lookup

[jasonrk]

Is there a way to disable IPv6 DNS Lookups? Queries to certain cites always return an IPv6 address:

----------------------------------------

NV3140#ping google.com

Type CTRL+C to abort.

Legend: '!' = Success, '?' = Unknown host, '$' = Invalid host address

        '*' = Request timed out, '-' = Destination host unreachable

        'x' = TTL expired in transit, 'e' = Unknown error

        'B' = Packet too big

Sending 5, 100-byte ICMP Echos to 2607:F8B0:4009:80F::200E, timeout is 2 seconds:

*****

Success rate is 0 percent (0/5)

-----------------------------------------

Is there a way to force the Adtran 3140 to use IPv4? Thanks!

Not really.  You just need to tell the application which version to use:

#ping

<cr>

ip                     - ICMPv4 ping

ipv6                   - ICMPv6 ping

twamp                  - Send TWAMP type ping to measure the packet loss, delay

                         and jitter

vrf                    - Send ICMP echo on the specified VRF

WORD                   - Ping destination (A.B.C.D, X:X:X:X::X, or hostname)

#ping ip google.com

Type CTRL+C to abort.

Legend: '!' = Success, '?' = Unknown host, '$' = Invalid host address

        '*' = Request timed out, '-' = Destination host unreachable

        'x' = TTL expired in transit, 'e' = Unknown error

        'B' = Packet too big

Sending 5, 100-byte ICMP Echos to 172.217.11.14, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms
