This text describes how the MX DNS query are resolved by ANDNA. It will be included in the final documentation, so feel free to correct it. But if you want to change the system here described, please contact us first.


In DNS server the MX field is provided by the DNS itself, to leave ANDNA more flexible the MX in Ntk is provided by the host itself. When you need to know the MX of a domain, you resolve the domain itself via a normal hostname resolution, then you contact the gained ip, which is the host itself and you ask its MX.

This requires small changes in the code: it is just necessary that the dsn_wrapper, after having resolved the main domain, contacts the host with and the node will reply with the MX field.

Easy and straight, that permits the hash_gnodes to understand only name resolving requests.
