Patent ID: 7864709

Claim:
A method for looking up location-specific configuration information for a network node, the method comprising: creating a Domain Name System (DNS) query packet at the network node, wherein the DNS query packet includes a DNS query field which includes the network node's address or the network node's subnet, wherein the DNS query field specifies a first service which is desired to be configured at the network node, and wherein the first service enables the network node to request a server to perform operations; sending the DNS query packet to a DNS server, wherein the DNS server is part of a distributed system which is designed to provide a name resolution service; receiving a DNS response packet from the DNS server, wherein the DNS response packet includes a first server's address, wherein the first server provides the first service which is desired to be configured at the network node; and storing the first server's address at the network node, thereby configuring the first service at the network node.
