Objective:

to extract hop that contain the last 10.88 ip address as per above example.

Desire Output:

HOST         HOP
192.168.1.1  10.88.28.134
....

Input will be from text file contain multiple Destination IP Address or direct IP. As below eample

Input.txt

192.168.1.1
192.168.5.31
192.168.65.3

Appreciate anyone can share powershell script for this.

function traceX
{
param ()
....
}

Syntax suggestion:

• Read from text file >> traceX -f c:input.txt -x 10.88
• Direct IP Address >> traceX 192.168.1.1 -x 10.88

While your exact requirements are still unclear, the following may get you started; it does NOT address your request for concurrency.
The function is intentionally kept simple; there is potential for better parameter handling using parameter sets and array parameters.

function traceX {
    param(
        [string] $FileOrIp,
        [string] $IpPrefix
    )
    # Determine if an IP address or a filename was passed.
    if ($FileOrIp -match '^d{1,3}.d{1,3}.d{1,3}.d{1,3}$') {
        $ips = $FileOrIp
    } else {
        $ips = Get-Content $FileOrIp
    }
    # Loop over all IPs
    foreach ($ip in $ips) {
        # Get the last matching hop and split the line into fields.
        # Note that the unary form of `-split` performs Awk-style splitting
        # by whitespace, which includes ignoring leading and trailing whitespace.
        $lastMatch = -split ((tracert -d -w 10 $ip) -match " $IpPrefix[^ ]+ $")[-1]
        # Get the last hop's IP.
        if (-not $lastMatch) {
            $matchedIp = 'Not Matched'
        } else {
            $matchedIp = $lastMatch[-1]            
        }
        # Output the result.
        [pscustomobject] [ordered] @{ HOST = $ip; HOP = $matchedIp }
    }
}
