You can find your ipv6 address from vps panel, remember you must open a support ticket to enable ipv6 at your vps . IPv6 is available at Nvme and hdd (normal network) plans in Los Angeles USA ( not for china optimized networks )
First, start and stop the VPS ( do not reboot), once IPv6 is assigned.
You must set up ipv6 manually as static or you will get very high ping and weird networking /slow speed as ipv6 auto setup via DHCP can have the wrong gateway IP. If you have not set up ipv6 before or do not work with ipv6 , we do not recommend using it .
Prefix length /64
Netmask /64
Gateway :
2607:fcd0:100:b101::1 or
2607:fcd0:100:e::1 or
2607:fcd0:100:b100::1 or
2607:fcd0:105:6b01::1
( for example if your assigned ipv6 is 2607:fcd0:100:b100:0000:0000:92fa:ac1a, then gateway is 2607:fcd0:100:b100::1 )
