spf for ipv6

[iamDonkey]

spf({
    sender: 'ceo@gmail.com',
    ip: '2607:f8b0:4864:20::b2b',
    helo: 'mail-yb1-xb2b.google.com',
    mta: 'mta.mydomain.com'
  }).then((sr) => {
      console.log(sr)
  }).catch(e=>{

  });

this giving result as softfail? i think it should be pass i also tried wrapping ip inside [ ] it gives neutral

Thanks, there seemed to be a bug in IPv6 CIDR range validation. This is now fixed in the latest version of mailauth:

$ mailauth spf -v -f ceo@gmail.com -i "2607:f8b0:4864:20::b2b" -e "mail-yb1-xb2b.google.com" -m "mta.mydomain.com"
