Одним из параметров команды Netsh interface ip set dnsявляется register. Какова его цель? Я не понимаю объяснения, приведенные в справке. Какое значение установлено для этого параметра, если я задаю конфигурацию DNS сетевого адаптера через графический интерфейс Windows?
Командная справка:
C:\Users\User>netsh int ipv4 set dns help Usage: set dnsservers [name=]<string> [source=]dhcp|static [[address=]<IP address>|none] [[register=]none|primary|both] [[validate=]yes|no] Parameters: Tag Value name - The name or index of the interface. source - One of the following values: dhcp: Sets DHCP as the source for configuring DNS servers for the specific interface. static: Sets the source for configuring DNS servers to local static configuration. address - One of the following values: <IP address>: An IP address for a DNS server. none: Clears the list of DNS servers. register - One of the following values: none: Disables Dynamic DNS registration. primary: Register under the primary DNS suffix only. both: Register under both the primary DNS suffix, as well as under the connection-specific suffix. validate - Specifies whether validation of the DNS server setting will be performed. The value is yes by default. Remarks: Sets DNS server configuration to either DHCP or static mode. Only when source is 'static', is the 'addr' option also available for configuring a static list of DNS server IP addresses for the specified interface. If Validate switch is yes, then the newly set DNS server is validated. Examples: set dnsservers name="Wired Ethernet Connection" source=dhcp set dnsservers "Wired Ethernet Connection" static 10.0.0.1 primary Он корректирует значения DNS в свойствах IPV4 для указанного интерфейса.
netsh interface ipv4 set dnsserver "Ethernet" static address=192.168.1.1 register=primary Устанавливает это при просмотре в Панели управления \ Все элементы панели управления \ Сетевые подключения:
