no communication - arp cache and netsh

Very strange - according to my new knowledge from Internet arp cache can be configured in two ways:
- arp command
- netsh interface ipv4 ... neighbors

I found a problem with arp cache - and It was new to me - that netsh interface ipv4 creating static values that will remain after restart and can't be removed by arp command, for example:

netsh interface ipv4 show neighbors

It looks like the same, but If I remove it from arp command it will return after restart - I must remove it from netsh command. What is very dangerous, that I can remove all static entries by single stuipid command:

netsh interface ipv4 delete neighbors

without any warning, just like throw to a black hole or null (*nix).
For Windows 2008/Vista arp cache managed by netsh was a dangerous way - without a fix it wasn't possible to remove this static entry.

netsh dhcp create scope

How to create dhcp scopes in older system - without dhcp module:

#create-DHCPScopes

$fileData = Get-Content c:\temp\scripts\some-file.txt

$fileData | %{
    # header of my file - tab is separator
    #  SHORT_SUBNET SUBNET_MASK  DHCP-LO      DHCP-HI      GW     NAME
    $line = $_
    $tabline = $line.Split("`t")
 

    $name = $tabLine[5]
    $dhcpName = """$name"""
    $description = "some descritpion"

    if ($tabline[0] -ne "SHORT_SUBNET") {
        netsh dhcp server add scope $tabLine[0] $tabline[1] $dhcpName $description
        netsh dhcp server scope $tabLine[0] set state 1
        netsh dhcp server scope $tabLine[0] set name $dhcpName
        netsh dhcp server scope $tabLine[0] set optionvalue 003 IPADDRESS $tabLine[4]
        netsh dhcp server scope $tabLine[0] set optionvalue 051 DWORD 2592000
        netsh dhcp server scope $tabLine[0] add iprange $tabLine[2] $tabLine[3]
    }
}
