IPv6 termination for external HTTP (S), SSL proxy and external proxy network balancers

Google Cloud allocates an IPv6 /64 address range to IPv6 transfer rules. Google Cloud cli Vespertie the IPv6 addresses with the least significant 64 bits defined on 0. However, the load balancer accepts traffic on the entire beach. Other IPv6 addresses of the load balancer can therefore be displayed in the allocated beach of X-Forceded-For headers depending on the IP address of IPv6 server to which the customer is connected.

DNSCHANGER FOR IPV4/IPv6

This app facto the Device Administrator Permission.
This is in no way required any only used to take uninstallation if Wanted by the User. No System Settings Are modified.
—————————–

Whilst it is fairly easy to add the dns servers used by your debate when using wifi, Android Offers no option to change the use DNS Servers when Using A Mobile Connection (2G/3G/4G etc.)).
This app Creates A VPN Connection Locally (No Data Leaves Your Phone Using This VPN Connection) to Use Your Configured DNS Servers On Both Wifi and Mobile Networks Without Needing Root Permissions.
Both ipv4 and ipv6 are usable, a feature which isn’t supported on many phones (even Android doesn’t offered ipv6 dns configuration in your wifi setings).

IPv6 termination for external http (s), SSL proxy and external proxy network balancers:

Noticed : Google Cloud accepts IPv6 traffic for direct strategy charging balancers with the external network loading to direct strategy based on the Backend service. To find out more, see the presentation page of the external network loading balancer with direct strategy based on a backend service.

Google Cloud accepts IPv6 customers with Proxy charging balancers, such as global external application loading and external network charging balancers. The load balancer accepts the IPv6 connections of users and plays the role of proxy to transmit them to backends.

You can configure ipv4 and IPv6 external IP addresses for the following load balancers:

• overall external application loading
• Classic application load balancer
• External proxy network load balancer

The IPv6 termination allows you to manage IPv6 requests for users by playing the role of proxy to transmit them via IPV4 to Backends. You can thus perform the following operations:

• Multi -regional deployment using a single IPv6 Anycast address. You only need a single IPV6 load balancing address for application instances executed in several regions. Your DNS server thus has a single AAAA recording. It is therefore not necessary to balance the load between several IPv6 addresses. Cache of AAAA recordings by customers is not a problem, because there is only one address to be cache. User requests sent to IPv6 address are automatically balanced in charge depending on the available capacity of the nearest operational backend.
• IPv6 customer traffic load balance via HTTP, HTTPS, HTTP/2, TCP and SSL/TLS.
• Exceeding capacity between regions using a single IPV6 load balancing address. If the backends in a region lack resources or are not operational, the overall load balancer automatically redirects user requests to the nearest region with available resources. As soon as the nearest region again has available resources, global load balancing restores dissemination via this region. Global load balancing requires using the premium level of network service levels.
• Execution of the double battery. To serve IPv6 and IPV4 customers, create two IP charging IP resources, one for IPv6 and the other for IPV4, then associate them with the same IPV4 application instances. IPV4 and IPv6 customers connect to IPV4 and IPv6 addresses respectively. These customers are then automatically balanced in charge according to the available capacity of the nearest operational backends. We provide free IPv6 transfer rules. Only the IPV4 rules are billed to you.

IPv6 and proxy termination

The configuration of the IPv6 termination of charging balancers allows you to display backends as IPv6 Applications with your IPv6 customers, as shown in the following figure.

Here is how the user’s connection process takes place to the load balancer via IPv6:

1. The load balancer, with its IPv6 address and its transfer rule, waits for users to connect.
2. An IPv6 client connects to the load balancer via IPv6.
3. The load balancer acts as a reverse proxy and ends the connection of the IPv6 customer. He places the request in an IPV4 connection which he transmits to a backend.
4. In the opposite direction, the load balancer receives the IPV4 response from the backend, then the place in the IPv6 connection which he transmits to the original customer.

IPv6 addresses allowance for the transfer of the load balancer

When you configure an external load balancer, you provide it with one or more global transfer rules, each with a public external IP address IPV4 or IPv6 (or both). You can use this IP address in the DNS records of your site.

When you create a transfer rule, you can either book a static IP address for your project, or automatically acquire an ephemeral IP address when creating the rule. A static IP address is reserved for your project. You can keep it until you release it voluntarily. The ephemeral address is associated with the transfer rule until you delete the latter. If you delete the transfer rule, the ephemeral address is released and returns to the Pool Google Cloud.

If you need IPV4 and IPv6 addresses for your load balancer, you can create two transfer rules, one associated with the IPV4 address and the other at IPv6 address. You can then associate the two rules with the same load balancer.

IPv6 address format

Google Cloud allocates an IPv6 /64 address range to IPv6 transfer rules. Google Cloud cli Vespertie the IPv6 addresses with the least significant 64 bits defined on 0. However, the load balancer accepts traffic on the entire beach. Other IPv6 addresses of the load balancer can therefore be displayed in the allocated beach of X-Forceded-For headers depending on the IP address of IPv6 server to which the customer is connected.

When formatting IPv6 addresses, Google Cloud follows the recommendations of section 4 of the RFC 5952 standard.

Customer’s IP address header with IPv6 termination for external application load balancers

When the load balancer plays the role of proxy to “convert” the customer’s IPv6 connection to an IPV4 connection to your backend, the original source IP address is replaced by the IP address of the load balancer. Nevertheless, the backends must often know the original source IP address for journalization, decision -making or other ends. Google Cloud provides an HTTP header that is propagated to backends and includes the original IPv6 customer address.

HTTP headers for IPv6 are similar to those for IPV4. The requests are in the following format:

• X-Forceded-For: Customer_ip_Address, Global_forwarding_rule_external_ip_Addresses

The last element corresponds to the IP address of the load balancer. The penultimate element indicates the client’s IP address as perceived by the load balancer. You can include other items in the X-Forceded-For header when the client or intermediate proxys add other X-Forceded-For heads before sending the request to the load balancer.

Here is an example of an X-Forceded-For header:

X-Forceded-For: 2001: DB8: ABCD: 1 :: 1234, 2607: F8B0: 4005: 801 :: 200E

2001: DB8: ABCD: 1 :: 1234 corresponds to the customer’s IPv6 address. 2607: F8B0: 4005: 801 :: 200E corresponds to the IPv6 address of the external application load balancer.

Prices

IPv6 termination transfer rules are provided free. Ephemeral IPv6 addresses are not billed to you. The reserved IPv6 addresses are billed at existing prices, whether or not they are used. The other pricing elements for IPv6 load balancing are identical to those of IPV4 load balancing. To find out more about load balancing pricing, see the network prices page.

Boundaries

• IPv6 traffic is not compatible with regional external external application balancers, internal interregional internal application loading, regional internal application loading, regional proxy proxy network loading, balancers, balancers regional external proxy network load and internal Passthrough network load balancers.
