For more\n information about configuring multiple network interfaces, see\n [Multiple network interfaces](/vpc/docs/multiple-interfaces-concepts).\n\n- The stack type of an VM's network interface determines the type of subnets\n to which it can connect:\n\n - IPv4-only interfaces can connect to dual-stack and IPv4-only subnets.\n - Dual-stack interfaces can connect to dual-stack subnets.\n - IPv6-only interfaces can connect to dual-stack and IPv6-only subnets.\n- To configure IPv6 addresses on a network interface, the interface must be\n connected to a dual stack or IPv6-only\n [subnet](/vpc/docs/subnets#subnet-types).\n\n- A subnet's IPv6 access type configuration determines whether the subnet has an\n internal or external IPv6 range. Connected instances inherit the IPv6 access\n type from the subnet.\n\n- IPv6-only instances are supported with only Ubuntu and Debian OS images.\n\nAccessing instances using IPv6 addresses\n----------------------------------------\n\nThe [implied IPv6 deny ingress firewall rule](/vpc/docs/firewalls#default_firewall_rules)\nprotects instances by blocking incoming connections to their IPv6 addresses.\nTo access instances using their IPv6 addresses, you must have a higher priority\nrule that allows incoming access.\n\nFor more information about firewall rules, see\n[VPC firewall rules](/firewall/docs/firewalls) and\n[Hierarchical firewall policies](/firewall/docs/firewall-policies).\n\nFor examples of VPC firewall rules, see\n[Configure firewall rules for common use cases](/vpc/docs/using-firewalls#rules-for-common-use-cases).\n\nIPv6 address assignment\n-----------------------\n\nThe following list describes how IPv6 addresses are assigned to compute\ninstances.\n\n- Compute instances are assigned an IPv6 address using DHCPv6. The metadata\n server responds to the instance's DHCPv6 requests and sends the first\n IPv6 address (`/128`) from the allocated `/96` range in response.\n\n- The metadata server uses route advertisement to publish the default route to\n the instance. The instance can then use this default route for all IPv6\n traffic.\n\n You can find the default route for an instance's network interface by\n connecting to the instance and querying the metadata server for the\n `gateway-ipv6` entry. \n\n ```\n curl http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/gateway-ipv6 -H \"Metadata-Flavor: Google\"\n ```\n\n For more information about the metadata server, see\n [View and query instance metadata](/compute/docs/metadata/querying-metadata).\n- Compute instances are configured with link local IP addresses, which are\n assigned from the `fe80::/10` range, but they are used only for\n [neighbor discovery](https://en.wikipedia.org/wiki/Neighbor_Discovery_Protocol).\n\n- The MTU configuration on the instance's network interface applies to both\n IPv4 and IPv6 packets, but not all MTU values are supported in all\n circumstances. For more information, see\n [Maximum transmission unit](/vpc/docs/mtu).\n\nCreate an instance that uses IPv6 addresses\n-------------------------------------------\n\nYou can create an instance that uses either a combination of IPv4 and IPv6\naddresses (*dual-stack*), or you can create an instance that uses only IPv6\naddresses.\n\nFor information about how to create a Compute Engine instance that uses\nIPv6 addresses, see the following tasks:\n\n- [Create a dual-stack instance](/compute/docs/instances/create-ipv6-instance#create-vm-ipv6-dual)\n- [Create an IPv6-only instance](/compute/docs/instances/create-ipv6-instance#create-vm-ipv6-only)\n\nChange the stack type of an instance\n------------------------------------\n\nYou can change the stack type of an existing Compute Engine instance.\nThe stack type can be set to either of the following:\n\n- IPv4 only (single stack)\n- IPv4 and IPv6 (dual-stack)\n\nIf you are changing the stack type to dual-stack, the instance must be connected\nto a dual-stack subnet. If you need to change which subnet the instance is\nconnected to, stop the instance and change the subnet. After the subnet is\nupdated, you can change the instance's IP stack type.\n\nYou can't change the stack type of an IPv6-only instance. \n\n### Console\n\n1.
