2) actual routing and performance of data exchanged between the available server nodes and external systems responsive to the data exchanged between the client devices and the available server nodes during use of the applications hosted by the available server nodes;
receiving a request from a client device for an IP address associated with a domain name, the client device having a client IP address;
querying a database of IP address location records to determine a geographic location of the client device;
determining geographic distance to available server nodes based on the geographic location of the client device; and
determining a first list of domain name system (DNS) records associated with the available server nodes, wherein the first list of DNS records is ordered based on the geographic proximity of the available server nodes to the geographic location of the client device;
determining a second list of DNS records associated with the available server nodes, wherein the second list of DNS records is ordered based on the performance of the available server nodes as determined by the performance information;
comparing the performance of the server nodes identified in the first list of DNS records and the performance of the server nodes identified in the second list of DNS records to determine whether performance of the server nodes identified in the second list of DNS records provides a threshold performance improvement over the server nodes identified in the first list of DNS records; and
delivering the first list of DNS records to the client device when the performance of the server nodes identified in the second list of DNS records does not provide a threshold performance improvement over the server nodes identified in the first list of DNS records; and
delivering the second list of DNS records to the client device when the performance of the server nodes identified in the second list of DNS records provides a threshold performance improvement over the server nodes identified in the first list of DNS records.

Abstract
Systems and methods for a DNS management system utilize a distance-based and/or a performance-based A record. A DNS management system of embodiments receives a request from a client for an IP address associated with a domain name. A database of IP address location records is queried to determine a geographic location of the client in operation according to embodiments. An A record corresponding to the geographically closest available server node may thereafter be delivered to the client. A system operable according to embodiments may additionally or alternatively monitor the performance of available servers and deliver an A record corresponding to the best performing local server.
