The service doesn't seem to support IPv6 as there are no AAAA DNS records.

  $ dog A AAAA fonts.bunny.net
  CNAME fonts.bunny.net.      10s   "bunnyfonts.b-cdn.net."
    A bunnyfonts.b-cdn.net. 10s   195.181.164.130
  CNAME fonts.bunny.net.       9s   "bunnyfonts.b-cdn.net."
    A bunnyfonts.b-cdn.net.  9s + 195.181.164.130
