SUPER HUB - CONFIGURING STATIC IP

A single dynamic public IP address will automatically be allocated to your Business Broadband service.

How do you configure IP addressing?

A single dynamic public IP address will automatically be allocated to your Business Broadband service. Please be aware that dynamic IP addresses can change if you reset the Super Hub or switch it off and on again. IP addressing within your network is then managed by the DHCP (Dynamic Host Control Program) server built into the Super Hub. Each connected device will be dynamically allocated an IP address when it is connected to one of your networks. Once allocated a private IP address, each of your devices can be used to communicate with other devices and services on your network and the public internet via Network Address Translation (NAT).

 

We can supply static IP addressing but this can only be provided if requested at the time of ordering. The available options are 1 address, 5 addresses or 13 usable public IP addresses. Multiple static IP addresses will be allocated as a sub-net of sequential addresses. Once allocated, IP address sub-nets cannot be extended. In the case that a larger allocation is required the old sub-net must be replaced with a new one. This will require re-configuration of the Gateway and the connected devices

 

How do you set-up reverse DNS?

Customers that have requested a Static IP address configuration from us, may wish to have a reverse DNS (Domain Name System) entry put in place on our nameservers. This is usually a requirement when sending email directly from your own server and provides an additional check for the recipients servers to validate the authenticity of your communication. Should you require this setup, please send an email to domainmanagement@virginmediabusiness.co.uk outlining the IP address and the hostname it is to be mapped to.

 

What network cables are needed?

If you are configuring your own office LAN, you’ll require suitable network cables. We recommend Cat6 Ethernet cables with straight through connection and RJ45 connectors at either end. If your network devices don’t support gigabit Ethernet, then Cat5 cables will be sufficient. These cables can be purchased in various lengths and colours from most electronic goods suppliers.
