An IP address is a number that is used to identify devices both on local networks and across the Internet. There are two commonly used types of IP addresses, IPv4 and IPv6. IPv4 addresses are 32 bits long while IPv6 addresses are 128 bits long. The WRVS4400N has the capability to allow you to use IPv6 addresses in your local network. This article explains the configuration of IP mode on an WRVS4400N router.
• WRVS4400N Wireless-N Gigabit Security Router
Configure IP Mode
Step 1. Log in to the web configuration utility and choose Setup > IP Mode. The lP Mode page opens:
Step 2. Click either the IPv4-only or the Dual-Stack IP Mode radio button.
• IPv4-only — Choose this option to only use IPv4 addresses on the local and public network.
• Dual-Stack IP — Choose this option to be able to use IPv6 and IPv4 addresses on the local network. Internet traffic will still use IPv4 addresses.
Timesaver: If you choose IPv4 Only, skip to Step 5.
Note: By default, the WRVS4400N supports 6to4 tunnels. A 6to4 tunnel allows your IPv6 network to connect to other IPv6 networks via IPv4 tunnels. There is no limit to the number of 6to4 tunnels that can be created unless you use the 6 to 4 Gateway Access Controls.
Step 3. Choose the appropriate 6 to 4 Gateway Access Control from the drop-down list.
• Disabled — This option will disable the 6to4 tunnel feature.
• Permit following sites — This option allows users to specify the IPv4 addresses of the sites that are to be permitted. Enter the IPv4 addresses in the available fields. Only IP addresses entered here will be able to create a 6to4 tunnel.
• Block following sites — This option allows users to specify the IP addresses of the sites that are to be blocked. Enter the IPv4 addresses in the available fields. This prevents this set of gateways to create a 6to4 tunnel with the router.
Step 4. Enter a static DNS entry that maps a hostname to an IPv6 address. This allows a user to use the domain names for IPv6 access even if there is no IPv6 DNS server in the network. Enter the domain name in the Domain field and the corresponding IPv6 address in the IP field.
Step 5. Click Save to apply changes.
