VPC release notes

When you reserve an internal range with an automatically allocated IPv4 CIDR block, you can specify the allocation strategy that is used to select a free block. This feature is available in General Availability.

VPC Network Peering supports peering connections in consensus mode. This feature is available in Preview. For more information, see Update strategy.

You can exclude IP address ranges from being used for automatic IP address allocation for internal ranges. This feature is available in General Availability. For more information, see Reserve internal ranges.

The following features of internal ranges are available in General Availability:

• Reserving internal ranges with IPv6 addresses
• Creating immutable ranges (ranges that can't be edited, except for the description)
• Editable descriptions

For more information, see Internal ranges overview.

When you reserve an internal range with an automatically allocated IPv4 CIDR block, you can specify the allocation strategy that is used to select a free block. This feature is available in Preview.

If you're a service producer that makes a service available through VPC Network Peering, you can migrate your service to Private Service Connect without changing the IPv4 address that consumers use to access the service. This feature is available in General Availability.

Support for the following is available in General availability for dual-stack configurations:

• IPv6 static routes with a next hop internal passthrough Network Load Balancer (next-hop-ilb)
• IPv6 static routes with a next hop instance identified by address (next-hop-address)

For more information, see Next hops and features in the static routes overview.

The following features of internal ranges are available in Preview:

• Reserving internal ranges with IPv6 addresses
• Creating immutable internal ranges (ranges that can't be updated, except for the description)
• Editable descriptions

For more information, see Internal ranges overview.

You can exclude IP address ranges from internal range automatic IP address allocation. This feature is available in Preview. For more information, see Reserve internal ranges.

You can create internal ranges that overlap with routes and subnets. This feature is available in General Availability. For more information, see Internal ranges overview.

The following Private Service Connect monitoring metrics are available for both producers and consumers in General Availability:

• Closed connections count
• Received packets dropped count
• Sent packets dropped count
• New connections count
• Open connections
• Received bytes count
• Received packets count
• Sent bytes count
• Sent packets count

Additionally, the NAT IP address capacity metric is available for producers in General Availability.

You can use these metrics to help monitor and troubleshoot published services, endpoints that connect to published services, and backends that connect to published services. For more information, see Monitor Private Service Connect connections.

VPC Flow Logs metadata annotations include InstanceGroupDetails. This feature is available in General Availability.

You can create an internal range with the usage type FOR_MIGRATION to migrate a CIDR range from one subnet to another. For more information, see Migrating subnet ranges. This feature is available in General Availability.

IPv6-only subnets and instances are available in Preview. For more information, see the following:

• Add an IPv6-only subnet
• Create an IPv6-only instance
• Types of subnets

For information about which services support IPv6-only configurations, see IPv6 support in Google Cloud.

Private Service Connect port mapping is available in General Availability. Port mapping lets consumer virtual machine (VM) instances privately communicate with specific service ports on specific producer VMs through a single Private Service Connect endpoint.

Support for IPv6 static routes with a next hop internal passthrough Network Load Balancer (next-hop-ilb) is available in Preview.

VPC Flow Logs includes the following metadata annotations in General Availability:

• src_gateway and dest_gateway
• src_google_service and dest_google_service
• load_balancing
• network_service
• psc

For more information, see Record Format.

The following producer load balancers now support all Private Service Connect monitoring metrics:

• Regional internal Application Load Balancer
• Regional internal proxy Network Load Balancer

In the Google Cloud Console, the Effective routes tab on the Routes page shows only routes that are effective. You can optionally show suppressed routes by using the Show suppressed routes toggle. You can also view the reason why a given route is suppressed. For more information, see List routes for a VPC network.
