Abstract
Method and systems to resolve IP addresses in response to domain name resolution requests on a packet-switched network. A request to resolve the domain name is received at a CDN in a second location. The domain name is associated with a content object and is relayed with a terminal device, which receives Internet access from an access network. The access network comprises a first DNS system that functions in an authoritative DNS mode. The content object is realized in a first location of the terminal device, different from the second location. An IP address for the domain name is returned from the second DNS system, wherein the second DNS system alternatively operates in both the authoritative and a recursing DNS mode. The content object is delivered from the second location with the CDN toward the terminal device.
