Elastic IP Addresses¶

Equinix Metal™ supports ordering additional static IP space (referred to as “Elastic IPs”) that can be moved easily between servers. You can choose to have both "local" and "global" elastic IP addresses, which you rent from Equinix Metal on an hourly basis.

• Elastic IPs - Clients can use our customer portal to order additional public IPv4 address space, ranging from a /32 (a single IP) through a /24 (256 IPs). Though there is no technical limit to how these IPs can be configured, we encourage you to use them responsibly, and as such we charge a nominal fee per elastic IP address ($0.005/hr or about $3.60/mo).

• Global Anycast IPs - Global Anycast IPs are public IPv4 addresses that are pulled from Equinix Metal-owned IP space and announced in all of Equinix Metal's core facilities. These IPv4 addresses cost $0.15/hr per IP. Regular $0.05/GB outbound rates apply, and (in addition) inbound bandwidth to Global Elastic IPs costs $0.03/GB.

Requesting Elastic IPs¶

Select the Project in which the reserved subnet is required. From within that specific project, from the IPs & Networks drop-down click IPs. Your project's current IP Addresses should be listed. To request additional IP Addresses, click Request IP Addresses.

From the slide out, you can select the size, type, and location of the reserved subnet. Be sure to include detailed information for the use case for the requested subnet.

Equinix Metal allows you to reserve the following sizes:

Provisioning a server with a single reserved subnet via Customer Portal¶

Provisioning a server with multiple reserved subnets via Customer Portal¶

Creating an IP Reservation through the API¶

curl  -v \
      -X POST "https://api.equinix.com/metal/v1/projects/$PROJECT_ID/ips" \
      -H 'Content-Type: application/json' \
      -H "X-Auth-Token: $METAL_API_TOKEN" \
      -d @- <<-'EOF'
      {
        "type": "public_ipv4",
        "quantity": 4,
        "comments": "for mytestserver.com",
        "metro": "sv",
        "details": "my /30 in AMS1"
      }
EOF

The quantity parameter should be the number of IPs in the subnet, valid values are 2, 4, 8, 16. IP reservations larger than 16 will require additional verification by Equinix Metal

Host IP Configuration¶

It is important to note that, unlike management IPs, elastic IPs are not automatically configured on servers by default. This is by design; as a security measure, as we do not maintain access to servers to update their network configuration files once they’re installed.

Using a sample IP address of 147.75.255.255, the following configuration will make the IP address usable on your server:

Ubuntu/Debian¶

To configure temporarily (won't come back up on reboot):

sudo ip addr add 147.75.255.255 dev lo

To make permanent, add to /etc/network/interfaces:

auto lo:0
iface lo:0 inet static
    address 147.75.255.255
    netmask 255.255.255.255

Ubuntu/Debian (netplan)¶

To configure temporarily (won't come back up on reboot):

sudo ip addr add 147.75.255.255 dev lo

To make permanent, add to /etc/netplan/00-elastic.yaml:

network:
  version: 2
  renderer: networkd
  ethernets:
    lo:
      addresses:
        - 127.0.0.1/8
        - 147.75.255.255/32

then either sudo netplan try or sudo netplan apply

CentOS¶

To configure temporarily (won't come back up on reboot):

sudo ip addr add 147.75.255.255 dev lo

To make permanent, add to /etc/sysconfig/network-scripts/ifcfg-lo:0:

DEVICE="lo:0"
BOOTPROTO="static"
IPADDR=147.75.255.255
NETMASK=255.255.255.255
NETWORK=147.75.255.255
ONBOOT=yes

If all goes well, you'll be all set to start using your Elastic IP as you please. If you feel there is something missing in this tutorial or anything is unclear, give us a shout!
