Does Facebook use IPv4 or IPv6?
Does Facebook use IPv4 or IPv6?
Over the past few years, Facebook has been transitioning its data center infrastructure from IPv4 to IPv6. We began by dual-stacking our internal network — adding IPv6 to all IPv4 infrastructure — and decided that all new data center clusters would be brought online as IPv6-only.
What IPv6 address should I use?
The 126-bit prefix is typically used for point-to-point links similar to the IPv4 address-conservative /30 allocation for point-to-point links. However, the address space in IPv6 is significantly larger than the IPv4 address space. The general recommendation is to use /64 on point-to-point links.
What is FE80 in an IPv6 address?
Typically, link-local IPv6 addresses have “FE80” as the hexadecimal representation of the first 10 bits of the 128-bit IPv6 address, then the least-significant 64-bits of the address are the Interface Identifier (IID).
How do I specify an IPv6 address?
Configuring IPv6 Addresses
- In the Managed Network node hierarchy, navigate to the Configuration > Interfaces > VLANs tab.
- Select a Vlan.
- Select the corresponding Vlan.
- Select the IPv6 tab and expand the IP Address Assignment accordion.
- Enable Use Static addresses.
- Click + in IPV6 addresses.
How do I find my IPv6 address from nslookup?
You can use the nslookup command to display IPv6 name service information. Under your user account, run the nslookup command. The default server name and address appear, followed by the nslookup command’s angle bracket prompt. Quit the nslookup command by typing exit .
Is Google a IPv6?
In the DNS servers field, enter the Google Public DNS IP addresses, separated by a comma: For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
Is it normal to have 2 IPv6 addresses?

Does IPv6 need gateway?
As more companies move away from IPv4 capabilities and toward using IPv6, it is critical to have a flexible, secure, adaptable gateway. The gateway address will be designated noting how traffic can be routed and managed.
How do I display IPv6?
Displaying the IPv6 route table
- To display the IPv6 route table, use the show ipv6 route command.
- To display a summary of the IPv6 route table, enter the show ipv6 route summary command.
- The command-line interface (CLI) output of the show ipv6 route summary command displays the following information.
Where is IPv6 address located?
IPv6 Locator. An IPv6 address is a 128 bytes address format, that will sooner or later replace the current Ipv4 format which is not scalable anymore for our needs. An example of Ipv6 address is: 0::24.24.24.24. If you are looking for IPv6 address lookup use IPGP IP Address Locator.
What are types of IPv6 addresses?
IPv6 addresses consist of the following types: unicast, anycast, and multicast. Unicast addresses identify a single interface. Anycast addresses identify a set of interfaces. A packet that is sent to an anycast address is delivered to a member of the set. Multicast addresses identify a group of interfaces.
What is benefit of IPv6 over IPv4 addresses?
Advantages of IPv6 over IPv4: Trillions of times more addresses will make it a mathematical certainty that in the future there will be orders of magnitude more devices with IPv6 than IPv4. IPv6 is easier to configure. IPv6 is compatible with 3G wireless (near) broadband and has other features that support greater mobility.
What is IPv6 IP address?
Internet Protocol Version 6 (or IPv6) is a successor of IPv4 Address standard developed by IETF, which is designed to solve IPv4 address exhaustion problem. IPv4 uses a 32-bit numbering scheme to represent an IP address, which has an address space of 232 or 4.3 billion.
