This application discloses a method and device for delivering full-volume multi-version DNS zone files. The method includes: if a new version of DNS zone files is obtained during the process of full-volume delivery, and a new full-volume delivery request is received, the old version of DNS files is determined to be transferred to the new version. The resource record involved in the update operation of the version DNS zone file is the target resource record; based on the target resource record, the update operation corresponding to the target resource record, and the data transmission block set corresponding to the old version DNS zone file, the multiplexed data transmission block and the new The data transfer block forms a data transfer block set corresponding to the new version of the DNS zone file; according to the new full-volume delivery request, the full-volume delivery of the data transfer block set corresponding to the new version of the DNS zone file. Based on the resource records involved in the update operation in the new version of the DNS zone file, the data transmission blocks in the data transmission block set corresponding to the old version of the DNS zone file are reused to the maximum extent to reduce the resource consumption of CPU and memory.

A method for automatically configuring a router (10) that has at least one upstream interface (11), connected or connectable to a higher-level subnetwork and / or a higher-level router, and at least one downstream interface (12), connected or connectable to a lower-level subnetwork (5), wherein it is monitored whether the router (10) receives, on the at least one upstream interface (11), messages providing notification of at least one domain, in particular as part of a DNS search list option (21), and, if no such message has been received over a prescribed period, a DNS island mode is automatically activated in which the DNS zone (22) of a local DNS server (14) of the router (10) is configured using a predefined island domain, and a transmission module (13) of the router (10) is prompted to send at least one message via at least one downstream interface (12), which message comprises the preconfigured island domain, in particular as part of a DNS search list option (31), and preferably an address (23) of the downstream interface (12). The invention furthermore relates to a method for automatic address configuration, a router (10), a computer program and a computer-readable medium.

Techniques for electronically signing DNS records stored in a zone file for an internet DNS zone are presented. The techniques include electronically accessing a plurality of DNS resource records of a DNS zone stored on one or more DNS servers of a distributed DNS database; generating a plurality of leaf nodes from the plurality of DNS resource records; constructing a recursive hash tree from the plurality of leaf nodes, where the recursive hash tree includes a plurality of nodes including a root node and the plurality of leaf nodes, where each node of the plurality of nodes includes either a leaf node or a hash of data including child nodes; storing the root node in a DNS key resource record for a zone signing key for the zone; and publishing, in a DNS resource record signature resource record, validation data including path data from the recursive hash tree.
