  • If you want ot learn how to do this yourself, subnet calculator (as mentioned by Denis Cooper) will not work for what you need.  Actually, its fairly easy.  If you are not aware of 'binary', you should familiarize yourself with that.  Then:

    You have 8 Bits per Octet in your subnet:


    which represented in binary is as:


    So then take the first 27 bits which would be the first 3 octets + the first 3 bits in the last octet:


    leaving the last 5 bits for your hosts: 00001

    Here's a tutorial that should help:
