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
