Abstract: System and methods are provided for encoding and encrypting DNS labels with content metadata and client metadata. A client computing device transmits a DNS query for the encoded domain name. A DNS server receives the encoded domain name and decrypts and decodes the domain name label. The DNS server uses the decrypted and decoded client and content metadata to make a routing decision to select a particular point of presence (PoP). The DNS server sends, to the client computing device, a DNS reply with the Internet Protocol (IP) address of the selected PoP. The client computing device requests content from the PoP identified by the provided IP address.

Abstract: A method of estimating a topography of at least first and second parts of a body may involve: causing at least one processor circuit to receive at least one signal representing at least one measurement of deformation of at least a portion of the body; causing the at least one processor circuit to associate the deformation with relative positions of at least the first and second parts of the body; and causing the at least one processor circuit to produce at least one output signal representing the relative positions of at least the first and second parts of the body. Systems are also disclosed.
