Use  ping to verify connectivity. Try a couple of known IPv4/IPv6 or IPv6-only hosts:

cbgb#ping ipv6.ote.gr
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2A02:580:200::200, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 40/40/44 ms
cbgb#
cbgb#
cbgb#ping www.ripe.net
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:610:240:22::C100:68B, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 96/96/100 ms
cbgb#

Observe the IP address being pinged It should be a v6 address.

Perform similar tests for IPv4-only sites
