Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.
HAProxy was written in 2000 [13] by Willy Tarreau, [14] a core contributor to the Linux kernel, [15] who still maintains the project. In 2013, the company HAProxy Technologies, LLC was created. [citation needed] The company provides a commercial offering, HAProxy Enterprise and appliance-based application-delivery controllers named ALOHA.
Round-robin DNS is an alternate method of load balancing that does not require a dedicated software or hardware node. In this technique, multiple IP addresses are associated with a single domain name; clients are given IP in a round-robin fashion. IP is assigned to clients with a short expiration so the client is more likely to use a different ...
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.
A fast-flux service network (FFSN) is a network infrastructure resultant of the fast-fluxed network of compromised hosts; the technique is also used by legitimate service providers such as content distribution networks (CDNs) where the dynamic IP address is converted to match the domain name of the internet host, usually for the purpose of load balancing using round-robin domain name system ...

DNS resolvers return the entire set upon query, but servers may implement round-robin ordering to achieve load balancing. In contrast, the Domain Name System Security Extensions (DNSSEC) work on the complete set of resource record in canonical order.
The load balancing provided by SRV records is inherently limited since the information is essentially static. The current load of servers is not taken into account unless TTL values are low enough (around a minute or lower) that the priority (or weight) values can be quickly updated.
