By default we will issue 1 static IP address per premises. We expect many users to install a gateway/router/firewall/WiFi hub on the end of the line and that will handle additional internal address allocations and use NAT to share the single address.If the user is taking VoIP services connected directly to our CPE switch then an additional IP address will be allocated for that. However we have no problem with allocating additional addresses or blocks of addresses if required so long as the end user knows what to do with them and makes a case to us. We have to justify our address blocks to RIPE who will want to see the case for assigning them. Given the shortage of IPv4 addresses we might be forced towards IPv6 numbering if a user wants to take a block but the B4RN network will support both protocol stacks.
