Hello
You have specified the pool as an address range beginning at
fd00:1:dead:beef::15 and ending at fd00:1:dead:beef::ffff. Which only
includes 65520 addresses to begin with. You use any of the following
alternatives:
1. increase the pool end address
2. specify it as address/length: fd00:1:dead:beef::/64
3. Add additional pools
You could specify it as fd00:1:dead::beef::15/64
