A method for establishing Segment Routing (SR) tunnel based on Internet Protocol version 6 (IPv6) data-plane using a path computation element communication protocol (PCEP) includes generating, by a path computation element (PCE), a first PCEP message, wherein the first PCEP message comprises indicating information and segment identifier (SID), and wherein the indicating information indicates that the SID is an IPv6 prefix of a node in a tunnel. A first path computation client (PCC) receives a first PCEP message from a PCE and the first PCC establishes an SR for IPv6 forwarding plane (SRv6) tunnel from the first PCC to a second PCC.

A wireless infrastructure that communicates with a DHCP server and a wireless client that rotates its MAC address performs a method including: upon receiving, from the wireless client, a first request with a first MAC address, creating a session context including the first MAC address and a stable identifier, and relaying the first request to the DHCP server; relaying, from the DHCP server to the wireless client, a first DHCP reply that includes an Internet Protocol (IP) address bound to the stable identifier; upon receiving, from the wireless client, a second request with the IP address and a second MAC address, merging the second MAC address and the IP address into the session context, and relaying, to the DHCP server, the second request including the stable identifier; and relaying, from the DHCP server to the wireless client, a second DHCP reply including the IP address bound to the stable identifier.

The present invention is directed to methods and systems for requesting information from a mobile device with a fencing agent. The fencing agent determines a position with a DNS resolver, queries geofences with an IP address, receives an anchor point with an IP address from the DNS resolver. The device with the fencing agent is able to receive multiple anchor points within multiple geofences within an ROI and translate fence points into fence geometries. Geofence information is stored and registered in a database of geofences, and each geofence is associated with a plurality of geographic designators, wherein each of the plurality of geographic designators is associated with an IP address.

Embodiments of this application provide a session management method, apparatus, and system. The method includes: receiving, by a first session management network element, a session request message from a second session management network element; allocating, by the first session management network element, Internet protocol IP information of a terminal device to a first session based on the session request message, where the first session is a branch of an established second session; and sending, by the first session management network element, the IP information of the terminal device to the second session management network element, where the IP information is used to obtain policy information corresponding to the IP information.

A Zero Touch Provisioning (ZTP) client, such as a network element, includes one or more processors and memory comprising instructions that, when executed, cause the one or more processors to configure an unnumbered interface to communicate via Internet Protocol version 6 (IPv6) and communicate to a server over a network, wherein the unnumbered interface is an interface which does not have an IPv6 address which is routable in the network, auto provision Open Shortest Path First version 3 (OSPFv3) based on a reply from a DHCPv6 relay agent, and request data from the network for provisioning.

The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node.

A session management function sends, to a network repository function, a first message requesting discovery of a user plane function supporting an uplink classifier functionality for a packet data unit session of a wireless device. The first message comprises an uplink classifier indication parameter. based on the first message, a second message comprising an identifier of the user plane function is received from the network repository function. A third message requesting a connection for the wireless device, between the session management function and the user plane function, is sent to the user plane function.

Various examples described herein are directed to identifying a particular computing device, such as a computing device having malware. A DNS query may be received with a token identifying an originating computing device. The DNS query may be compared to a list of domain names associated with particular characteristics, such as having malware. The token may be used to identify the originating computing device and perform further actions.

Disclosed are a Cluster Trivial Database (CTDB)-based virtual Internet Protocol (IP) address allocation method and apparatus, a distributed storage device, and a computer-readable storage medium. The method is applied to a distributed storage cluster. A known IP Version 4 (IPV4) virtual IP address parameter and available IPV4 virtual IP address parameter corresponding to an IPV4 virtual IP address and a known IP Version 6 (IPV6) virtual IP address parameter and available IPV6 virtual IP address parameter corresponding to an IPV6 virtual IP address may be acquired to obtain an IPV4 allocation result and an IPV6 allocation result by calculation respectively, and then virtual IP addresses are allocated to each normal node by use of the IPV4 allocation result and the IPV6 allocation result.

The invention relates to discovering and clustering Internet protocol addresses. For example, the invention can include discovering an IPv6 address of an Internet-facing device on a network, where the IPv6 address is associated with a wide area network (WAN) media access control (MAC) address and a WiFi basic service set identifier (BSSID), identifying an associated BSSID in WiFi geolocation databases based on the WAN and WiFi BSSID, and geolocating the Internet-facing device by retrieving a location record in the WiFi geolocation databases for the associated BSSID.
