Some embodiments provide systems and methods for determining a server of a distributed hosting system to optimally distribute content to an end user. The method includes identifying an IP address of the end user. Based on the IP address, a set of servers send packets to the end user to derive performance metrics. The performance metrics are used to determine a server from the set of servers that optimally distributes content to the end user. The method modifies a configuration for resolving end user requests such that the optimal server is identified to the end user when the end user requests content from the hosting system. Some embodiments determine the optimal server by providing downloadable content that is embedded with a monitoring tool. The monitoring tool causes the end user to derive performance metrics for the hosting system when downloading a particular object from a set of servers.

1. A method for determining from a plurality of distributed servers operated by a hosting system, a server to optimally distribute content to a particular end user, the method comprising: receiving a domain name system (DNS) request comprising the Internet Protocol (IP) address of the particular end user in addition to or instead of the IP address of a DNS resolver used by the particular end user;extracting the IP address of the particular end user from the DNS request;identifying sets of performance metrics measuring performance related to distribution of content to the IP address of the particular end user from each server of a set of the plurality of distributed servers of the hosting system;determining a particular server from the set of distributed servers that optimally distributes content to the particular end user by analyzing the sets of performance metrics; andmodifying a configuration for resolving the DNS request from the particular end user such that an IP address of the particular server that optimally distributes content to the particular end user is provided in response to the DNS request. 2. The method of claim 1, wherein determining the particular server to optimally distribute content comprises determining a first optimal server and a second optimal server and wherein modifying the configuration further comprises modifying the configuration such that the first server is identified when the first server is available and the second server is identified for redundancy when the first server is unavailable. 3. The method of claim 1, wherein modifying the configuration further comprises modifying at least one of a DNS resolution table and configuration file of an authoritative DNS name server of the hosting system to identify the particular server when resolving the DNS request from the particular end user. 4. The method of claim 1, wherein the sets of performance metrics comprise a latency measurement for sending a packet from a server of the set of servers to the particular end user. 5. The method of claim 4, wherein the sets of performance metrics further comprise at least one of a cost measurement and a proximity measurement for sending the packet from the server to the particular end user. 6. The method of claim 4, wherein the sets of performance metrics further comprise at least one of a time of day traffic measurement and identification of an optimal route from a plurality of routes for sending the packet to the particular end user. 7. The method of claim 1, wherein the hosting system comprises a first set of servers that distribute hosted content to end users and a second set of servers that resolve end user requests for content that is hosted by the hosting system, and wherein the particular server is a server of the first set of servers. 8. The method of claim 7, wherein the hosting system further comprises a third set of servers for deriving the sets of performance metrics related to distributing content from the first set of servers to the particular end user. 9. The method of claim 8, wherein the third set of servers comprises (i) at least two servers of the first set of servers or (ii) at least two servers that augment functionality of the first set of servers. 10. A method for determining from a plurality of servers operated by a hosting system, a server to optimally distribute content to a client, the method comprising: with at least an authoritative domain name system (DNS) server of the hosting system comprising a processor and non-transitory computer-readable storage: receiving a DNS request that is modified to include the Internet Protocol (IP) address of the client in addition to or instead of the IP address of a DNS resolver used by the client to forward the DNS request to the authoritative DNS server of the hosting system;extracting the IP address of the client from the DNS message;determining an optimal server from the plurality of servers that optimally services the IP address of the client; andpassing an IP address of the optimal server to the client in response to resolving the DNS request. 11. The method of claim 10, wherein the DNS request is an EDNS message comprising an extension to the DNS message that is configured to carry the IP address of the client. 12. The method of claim 10 further comprising compiling sets of performance metrics from each server of the plurality of servers, the sets of performance metrics measuring performance related to distribution of at least one common packet to the IP address of the client from each server of the plurality of servers. 13. The method of claim 12, wherein the optimal server is a first server, the method further comprising determining from the sets of performance metrics, a second server from the plurality of servers that services the IP address of the client more optimally than the first server. 14. The method of claim 13 further comprising modifying a DNS resolution table that is used by the authoritative DNS server to resolve DNS requests and that is stored to the non-transitory computer-readable storage of the authoritative DNS server, wherein modifying the DNS resolution table comprises changing the optimal server that is selected for the IP address of the client from the first server to the second server. 15. The method of claim 12, wherein each server of the plurality of servers derives a set of performance metrics by (i) sending at least one packet to the IP address of the client without the client requesting the at least one packet from each server of the plurality of servers and (ii) measuring at least one performance metric related to the sending of the packet.
