It’s important to think about how many IPs are going to be used by ISP equipment – in an example of a leased line, if you are provided with one router, typically, that device will use one public IP address and that address will become your default gateway. Don’t worry, if necessary we can help with any IT consultancy tasks around configuration and setup. You would then allocate the remaining 6 IPs to devices, such as the gateway router, firewalls, specific NAT rules, servers, etc. ![]() For example, you would request a “/29” subnet from your ISP, and you would be provided with a subnet of 8 IP Addresses, 6 of which are usable – this is because 1 is the network address (the first IP) and one is the broadcast address (the last IP). To specify the subnet, a CIDR (Classless Inter-Domain Routing) notation is used. IPs are deployed as part of a subnet, or as your ISP may call it informally, an “IP block”. When commissioning internet connections, one important aspect is calculating how many public IP addresses (IPs) are needed to fulfil all of the business IT requirements.
