Dnsmasq is a lightweight, easy to configure DNS forwarder, designed to provide DNS (and optionally DHCP and TFTP) services to a small-scale network. It can serve the names of local machines which are not in the global DNS. Dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server.
Forward-confirmed reverse DNS (FCrDNS), also known as full-circle reverse DNS, double-reverse DNS, or iprev, is a networking parameter configuration in which a given IP address has both forward (name-to-address) and reverse (address-to-name) Domain Name System (DNS) entries that match each other. This is the standard configuration expected by ...
Some anti-spam filters assume that email that originates from such addresses is likely to be spam, and may refuse connection. [6] [7] A forward-confirmed reverse DNS (FCrDNS) verification can create a form of authentication showing a valid relationship between the owner of a domain name and the owner of the server that has been given an IP address.
dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance, and can be configured to automatically pick up the addresses of its upstream servers. dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server.
The characteristic payload information of an MX record [1] is a preference value (above labelled "Priority"), and the domain name of a mailserver ("Host" above).. The priority field identifies which mailserver should be preferred - in this case the values are both 10, so mail would be expected to flow evenly to both onemail.example.com and twomail.example.com - a common configuration.

Each service instance is described using a DNS SRV [17] and DNS TXT [18] record. A client discovers the list of available instances for a given service type by querying the DNS PTR [ 18 ] record of that service type's name; the server returns zero or more names of the form <Service>.<Domain>, each corresponding to a SRV/TXT record pair.
