[Lab2]: Disable IPv6
After trying many fixes to use IPv6 after rebooting from Windows we gave up without it working.
The IPv6 should be disabled on LAB2 computers and after doing that, some services should be changed too:
- The AAAA record should be removed from
lab2pX
; - The DHCP server config should be updated;
- GlusterFS should use IPv4 instead of IPv6;
