You could save it as a module which is a psm1 file. Check your module locations: $env:PSModulePath -split ";"

I tend to put it in C:\Program Files\WindowsPowerShell\Modules\**Your Function Name**

then you can just load the module when you open powershell by doing 'import-module DHCP' in your case.
