How to check whether IPV6 enabled or not?

root@master:/etc# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:1d:09:f2:56:d6
inet addr:172.16.188.155 Bcast:172.16.188.255 Mask:255.255.255.0
inet6 addr: fe80::21d:9ff:fef2:56d6/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:380 errors:0 dropped:0 overruns:0 frame:0
TX packets:138 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:69003 (67.3 KB) TX bytes:30542 (29.8 KB)
Interrupt:16 Memory:f8000000-f8012100
That means your IPV6 is enabled. If your IPV6 disabled the result should like this:
root@master1:~# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:1d:09:f2:56:d6
inet addr:172.16.188.155 Bcast:172.16.188.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:186 errors:0 dropped:0 overruns:0 frame:0
TX packets:61 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:37514 (36.6 KB) TX bytes:8590 (8.3 KB)
Interrupt:16 Memory:f8000000-f8012100
