    How to validate the IP address using PowerShell?



    To validate the IP address using PowerShell, we can use several methods as shown below.

    • Using RegEx method.

    • Using Typecasting method.

    Using TypeCasting method.

    In this method, we are using System.Net method class IPAddress to validate the IP address.

    [ipaddress]$IP = "192.168.0.1"

    The above one is valid. Let’s check what $IP stores in.

    PS C:\> $IP
    
    Address : 16820416
    AddressFamily : InterNetwork
    ScopeId :
    IsIPv6Multicast : False
    IsIPv6LinkLocal : False
    IsIPv6SiteLocal : False
    IsIPv6Teredo : False
    IsIPv4MappedToIPv6 : False
    IPAddressToString : 192.168.0.1

    The above one is Ipv4 and this method also works for IPv6. See the example below.

    PS C:\> [ipaddress]"2001:0db8:85a3:0000:0000:8a2e:0370:7334"
    
    Address :
    AddressFamily : InterNetworkV6
    ScopeId : 0
    IsIPv6Multicast : False
    IsIPv6LinkLocal : False
    IsIPv6SiteLocal : False
    IsIPv6Teredo : False
    IsIPv4MappedToIPv6 : False
    IPAddressToString : 2001:db8:85a3::8a2e:370:7334

    You can notice the difference in AddressFamily property in both the address.

    If we enter the wrong range of IP addresses.

    PS C:\> [ipaddress]"192.168.0.256"
    Cannot convert value "192.168.0.256" to type "System.Net.IPAddress". Error: "An invalid IP address was specified."
    At line:1 char:1
    + [ipaddress]"192.168.0.256"
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : InvalidArgument: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvalidCastParseTargetInvocation

    It rejects the IP input. You can also use this method in function to validate the IP.
