Thanks. We'll let you know when a new response is added.

Well, I’m supprised you’re not using DHCP for address allocations. If you were using DHCP the computers would just get all the information they need automatically.

The use of a 29bit address is key here. However you will still have available addresses on a 29bit address if you currently only have 6 computers connected.

If i were you I would check with your central computer services as which address pool they would want to use rather than go against a company policy.

    If you have 6 and need 10 more, you need addressing for 16 hosts. You won't be able to do better than 172.16.1.0/27 which should accommodate 30 addresses. Since there are no "fractional" /CIDR values possible, you can't fall back to /28 which would only allow 14 addresses. Tom

    In order for address space to handle 16 computers, you need to change the subnet mask to 172.16.1.0/27 (255.255.255.224).
