Commands

Indented.Net.Dns provides a number of commands to execute DNS queries against name servers.

Get-Dns

Get-Dns [[-Name] <String>]
        [[-RecordType] <RecordType>]
        [-RecordClass <RecordClass>]
        [-NoRecursion]
        [-DnsSec]
        [-EDns]
        [-EDnsBufferSize <UInt16>]
        [-NoTcpFallback]
        [-SearchList <String[]>]
        [-Tcp]
        [-Port <UInt16>]
        [-Timeout <Byte>]
        [-IPv6]
        [-ComputerName <String>]
        [-DnsDebug]

Get-DnsVersion

Short-cut to execute a query for bind.version.

Get-DnsVersion [-Tcp]
               [[-Port] <UInt16>]
               [-IPv6]
               [[-ComputerName] <String>]

Equivalent to:

Get-Dns -Name bind.version. -RecordType TXT -RecordClass CH

Get-DnsZoneTransfer

Get-DnsZoneTransfer [-ZoneName] <String>
                    [-SerialNumber <UInt32>]
                    [-Port <UInt16>]
                    [-Timeout <Byte>]
                    [-IPv6]
                    [-ComputerName <String>]

Search-Dns

Uses Get-Dns to search the authoritative name servers of a zone for a specific record.

Search-Dns [-Name] <String>
           [-ZoneName] <String>
           [[-RecordType] <RecordType>]
           [-Tcp]
           [-Port <UInt16>]
           [-IPv6]
           [-ComputerName <String>]

Trace-Dns

Performs an iterative search for a record from either root hints of a specified DNS server.

Trace-Dns [-Name] <String>
          [-ZoneName] <String>
          [[-RecordType] <RecordType>]
          [-Tcp]
          [-Port <UInt16>]
          [-IPv6]
          [-ComputerName <String>]
