// Although fullName is already a DNS subdomain, we can't just cut it
// at N characters and expect another DNS subdomain. That's because
// we might cut it right after a ".", which would give an invalid DNS
// subdomain (eg. test.-<hash>). So we make sure the last character
// is an alpha-numeric character.
