Layered Service Provider (LSP) is a deprecated feature of the Microsoft Windows Winsock 2 Service Provider Interface (SPI). A Layered Service Provider is a DLL that uses Winsock APIs to attempt to insert itself into the TCP/IP protocol stack.

The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing. [1] These mechanisms use TSIG to provide security. The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the RFC 2136 standard for updating DNS records.
While Winsock is a user mode library, it uses a kernel mode driver, called Ancillary Function Driver (AFD) to implement certain functionality. Winsock Kernel (WSK) A kernel-mode API providing the same socket-and-port abstraction as Winsock, while exposing other features such as Asynchronous I/O using I/O request packets.

Whilst DNS lookups read DNS data, DNS updates write them. Both workstations and servers running Windows attempt to send Dynamic DNS update requests to DNS servers. Workstations running Windows attempt to register their names and their IP addresses with DNS servers, so that other machines may locate them by name.
During the oxygen therapy in the chamber, air pressure is increased 2 to 3 times higher than normal air pressure. Hyperbaric chambers can be used for life-saving, limb-saving, and tissue-saving ...
The response to a successful TSIG update will also be signed with a TSIG record. Failures are not signed to prevent an attacker from learning anything about the TSIG key using specially crafted update "probes". The nsupdate program can use TSIG to do DNS updates. The TSIG record is in the same format as the other records in the update request.
