IPv6 Gateway

An IPv6 gateway is a device that uses the newer IPv6 (Internet Protocol version 6) standard rather than IPv4 to transmit data.

What is an IPv6 Gateway?

An IPv6 gateway transmits data over the newer IPv6 standard. IPv6 provides better security and many more available addresses for internet-connected devices.

The IPv6 protocol is different from the older IPv4 protocol, and offers improved support for device connection and transmission speeds. A gateway is a device that provides connectivity between networks, translating and routing information as it goes.

An IPv6 proxy has many of the same attributes as an IPv6 gateway. Both are implemented in either software or hardware, and both can translate between IPv6 and IPv4 addresses. One key difference between a proxy and a gateway is that a proxy conceals the network behind it and can block traffic for security reasons, while a gateway is more like a door through which data can flow.

Why Are IPv6 Gateway Capabilities Important?

The number of possible IP addresses under the IPv4 standard is a lot smaller than the possible number of addresses under the IPv6 standard. With IPv6 we have a reliable, scalable and cost-effective way to connect networks.

Since the majority of new addresses are now used up, it is no longer possible to get a new IP address. As more companies are moving away from using IPv4, it is critical to have a flexible, secure, adaptable gateway.

Traffic routing is an important function of any network, and it’s a gateway address that’s critical to the design of a network. With the IPv6 Gateway you have many of the advantages of the IPv6 Network without the disadvantages of the IPv6 Network.

How Does an IPv6 Gateway Work?

Where IPv4 uses 32-bit addresses, usually written as a set of four decimal numbers separated by dots, IPv6 uses 128-bit addresses. As a result, IPv6 addresses are much longer. They are made up of several parts.

NAT allows companies to use the same IP address for multiple users. But because of security risks that NAT presents, some companies are choosing not to use it. NAT works by translating private, unregistered IP addresses in a local network to a single public IP address. It then adds a fixed routing rule so that requests are routed from the local network directly to the NAT server.

NAT, however, doesn’t work very well for large numbers of some types of IP addresses, or in a network with a large number of devices. The best solution is to transition to IPv6, so that the network is optimized for top functionality, flexibility, and security.

How does F5 handle IPv6 gateways?

The F5 IPv6 Gateway is an advanced load-balancing appliance that’s a part of the F5 BIG-IP product family. It’s optimized for the new IPv6 Internet Protocol. The F5 IPv6 Gateway enables enterprises to simultaneously support both the current generation of IPv4 devices as well as emerging IPv6 devices, while seamlessly handling migration to IPv6.

IPv6 is designed to support future internet protocol requirements. AppViewX provides an automated workflow to ensure the organization can deploy IPv6 migration plans and meet application availability requirements without disrupting their existing networks.

What is IPv6 proxy?

An IPv6 proxy is a device or software that sits on the edge of a network to translate IPv4 (Internet Protocol version 4) to IPv6. Both protocols are in common use today, and an IPv6 proxy ensures traffic using both can be managed.

IPv6 proxy
An IPv6 proxy intercepts traffic and translates the protocols used to ensure that Internet service providers, carriers, and organizations can connect and process all appropriate traffic, regardless of whether it uses the older Internet Protocol or the newer version introduced in 2012.
The new IPv6 standard, which many people are calling IPv8, uses a different, longer IP addressing configuration and much more besides. An IPv6 proxy has many of the same properties as an IPv6 gateway. It can be implemented in either software or hardware, and it can support IPv4 to IPv6 address translation.

A key difference between proxies and gateways is that proxies conceal the networks behind them and are often used for security reasons. Gateways, by contrast, are more like doors and allow traffic to pass through. Gateways define the edge of a network and the protocols and configurations in use, but generally do not perform any filtering, merely translating and routing information.

Why Are IPv6 Proxy Capabilities Important?

The number of possible Internet Protocol (IP) addresses under the IPv4 standard is many orders of magnitude smaller than the possible IP addresses under the IPv6 standard.

Given the explosive growth of the Internet since its origins, and the number and types of devices that can connect to it, the IPv6 standard was developed to alleviate the expected exhaustion of possible IP addresses. New IPv4 addresses are no longer available.

Although IPv6 offers a number of significant advantages, such as simplified routing and packet headers, over half of all Internet traffic still uses the IPv4 standard. As more companies migrate to IPv6, they need to ensure that they continue to meet the needs of their customers, partners, and employees who use IPv4.

Some websites that use both IPv4 and IPv6 have established mechanisms for users to access them with either protocol. To deploy a proxy, administrators need to install an application that supports two types of devices and connect to the Internet via both wired and wireless connections.

How Does an IPv6 Proxy Work?

The IPv4 standard uses 32-bit addresses in the familiar four-part configuration—, for instance. IPv6 addresses are 128 bits in length, thus four times as long, in a configuration that can be abbreviated using two colons together (::) but that in full looks like 0000:0000:0000:0000:0000:ffff:cb00:7100, for instance.

ipv6 explained

IPv4 addresses can be converted into IPv6 addresses. There is no such thing as “backwards translation” from IPv4 to IPv6. With IPv6, IPv4 traffic is intercepted and translated before being forwarded on to IPv6 servers. Network address translation (NAT) is one method that has extended the life of IPv4 while service providers and organizations gradually shift to the new standard, usually through a period of using both in parallel.

NAT is used to translate private, unregistered IP addresses on a local network to one single public IP address which can connect to the Internet. In this way, an IPv6 proxy forwards packets from an IPv6 network to an IPv4 network, and vice versa.

How Does F5 Handle IPv6 Proxies?

The F5 BIG-IP platform operates as a full proxy server, sitting between clients and a server to manage requests and, sometimes, responses. Because it runs directly on Amazon VPC instances, it can function as a native IPv4-to-IPv6 gateway, managing application delivery in both networking topologies.

The F5 BIG-IP® Local Traffic Manager (LTM) provides IPv6 Gateway Services by passing IPv6 traffic through the device, and using a tunnel to connect. AppViewX ADC+ allows organizations to implement IPv6 migration plans and meet application availability requirements without disrupting current network infrastructures.
