Basic IPv6 troubleshooting

Most IPv6 connectivity problems are caused by a typo, an incorrect prefix length, the wrong location gateway, or the wrong network interface.
Each VPS receives its own /64-equivalent IPv6 allocation, but it is not a separately routed /64. Configure every assigned IPv6 address on the VPS with a /48 prefix length so it can reach the location-specific gateway.
Use the exact IPv6 allocation and gateway shown in your welcome email or under Network Info in the VPS Management Portal.

​
Check the configured address

On Debian and other Linux systems, run:
Example output:
Confirm that:
  • The address belongs to the allocation assigned to this VPS
  • The address uses the /48 prefix length
  • The expected network interface is up
  • No more than 20 IPv6 addresses are configured simultaneously

​
Check the default route

Run:
Example output:
Confirm that the gateway exactly matches the location-specific gateway shown in the VPS Management Portal. Do not derive or guess it from the example.

​
Test external connectivity

Use a well-known IPv6 destination:
If the address, /48 prefix length, gateway, and interface are correct but IPv6 still does not work, contact EDIS Global Support and include the command output.
Rotating or randomly generated IPv6 addresses and IPv6 proxy address cycling are prohibited. Review the Acceptable Use Policy before configuring multiple addresses.
