Description

The Resolve-DnsName cmdlet performs a DNS query for the specified name. This cmdlet is functionally similar to the nslookup tool which allows users to query for names.

Examples

EXAMPLE 1

PS C:\> Resolve-DnsName -Name www.bing.com

This example resolves a name using the default options.

EXAMPLE 2

PS C:\> Resolve-DnsName -Name www.bing.com -Server 10.0.0.1

This example resolves a name against the DNS server at 10.0.0.1.

EXAMPLE 3

PS C:\> Resolve-DnsName -Name www.bing.com -Type A

This example queries for A type records for name www.bing.com.

EXAMPLE 4

PS C:\> Resolve-DnsName -Name www.bing.com -DnsOnly

This example resolves a name using only DNS. LLMNR and NetBIOS queries are not issued.
