Detailed explanation of the Get command used to obtain information in PowerShell

There are many Get commands in PowerShell for getting information. Here are some commonly used Get command examples:

Get-NetIPAddress -AddressFamily IPv6: This command will return all IPv6 address information on the computer, including interface index, IP address, prefix length, etc.

Get-NetIPAddress -AddressFamily IPv6Command output information,

 IPv6 address information (Get-NetIPAddress -AddressFamily IPv6)

IPv6 address Interface index Interface alias Address Type Prefix length Prefix source Suffix source Address status Validity period Preferred deadline Is it possible as source address Policy storage

Get-NetIPAddress -AddressFamily IPv6The command is used to list all IPv6 addresses in the system. The following are the commonly used options and functional categories of this command and organize them into tables:

These terms are related to network protocols and IPv6 settings, usually commands and parameters related to network configuration in Windows PowerShell. Here is a detailed explanation of these terms:

Get-NetIPv6Protocol：

  • This is the PowerShell command to get the settings and configuration of the current IPv6 protocol.
  • DefaultHopLimit：
  • The default hop limit indicates the maximum number of routing nodes that a packet can pass through in an IPv6 network. The default value is usually 64.
  • NeighborCacheLimit(Entries)：
  • Neighbor cache limit, indicating the maximum number of entries that an IPv6 neighbor cache (used to store device information in the local network) can contain.
  • RouteCacheLimit(Entries)：
  • Routing cache limit, indicating the maximum number of entries that can be included in the IPv6 routing cache.
  • ReassemblyLimit(Bytes)：
  • Reorganization limit, indicating the maximum number of bytes allowed during IPv6 packet reorganization. IPv6 packages commonly used to handle shards.
  • IcmpRedirects：
  • ICMP redirection refers to whether IPv6 routers are allowed to send ICMP redirect messages to inform the host to use different routing paths.
  • SourceRoutingBehavior：
  • Source routing behavior refers to whether IPv6 allows source routing. The source route allows the sender to specify the routing path for the packet.
  • DhcpMediaSense：
  • DHCP media perception refers to whether the network interface automatically configures the IP address through DHCP when there is an available network.
  • MediaSenseEventLog：
  • Media-aware event log is used to record changes in connection status of network interfaces (such as disconnection, connection, etc.).
  • MldLevel：
  • Multicast Listening Protocol (MLD) level, used to define the management level of IPv6 multicast group membership.
  • MldVersion：
  • The MLD version refers to the version used by the Multicast Listening Protocol (MLD) (such as v1 or v2).
  • MulticastForwarding：
  • Multicast forwarding refers to whether the forwarding function of IPv6 multicast packets is enabled. When enabled, multicast traffic can be forwarded on the network.
  • GroupForwardedFragments：
  • Group forwarding sharding refers to the forwarding behavior of sharded data packets in IPv6 multicast group.
  • RandomizeIdentifiers：
  • Randomization identifier refers to whether to enable the generation of randomized interface identifiers (such as randomization of MAC addresses) in IPv6 to improve privacy.
  • AddressMaskReply：
  • Address mask reply refers to whether the IPv6 protocol allows the sending of address mask reply messages, which are used to confirm the network mask.
  • UseTemporaryAddresses：
  • Use temporary addresses, which means whether temporary IPv6 addresses are enabled (usually used to enhance privacy) are not used for long-term communications.
  • MaxTemporaryDadAttempts：
  • The maximum number of temporary address duplicate address detection (DAD) attempts refers to the maximum number of times when generating temporary IPv6 addresses, whether the same address is repeated.
  • MaxTemporaryValidLifetime：
  • The maximum valid life cycle of temporary IPv6 addresses refers to the maximum validity period of temporary IPv6 addresses.
  • MaxTemporaryPreferredLifetime：
  • The preferred life cycle of the maximum temporary address refers to the maximum life cycle of the temporary IPv6 address before entering the "preferred" state.
  • TemporaryRegenerateTime：
  • The temporary address regeneration time refers to the regeneration interval when the IPv6 temporary address reaches its maximum effective life cycle.
  • MaxTemporaryDesyncTime：
  • The maximum temporary address is out of synchronization time, which refers to the maximum time that the IPv6 address is allowed to be out of synchronization during the temporary validity period.
  • DeadGatewayDetection：
  • Dead gateway detection refers to whether IPv6 enables the dead gateway detection function. If the gateway is unreachable, the system will try to switch to other available gateways.
  • Most of these parameters are used for the configuration and management of network interfaces and IPv6 protocols, affecting IPv6 routing, address allocation, connectivity and privacy settings.
