Title: Error: Unable to find a unique /48
Post by: mbpkg on November 05, 2019, 01:01:56 AM
Hello all,

I am unable to allocate a routed /48 subnet for my tunnel through the Stockholm tunnel server.  I receive the response "Error: Unable to find a unique /48".  What is the correct procedure for addressing this?  I'm happy to contact support or try a different tunnel server, but I thought I should ask here first.

Thanks!

I would let ipv6@he.net know so they can tell you what to do or fix it

Probably just the bindings for that server's pool being too sticky right...? Does HE automatically reap tunnels that are not used at all for years and years?

Not certain, but HE does periodically ping the client tunnel endpoint to see if it's still there using the tunnel /64 ...::2 address.  Upon sufficient failure, a tunnel may be marked inactive, but it's not returned to the pool.
