IP Address Allocation
Depending on your routing configuration, you need the following subnets:
- A LAN subnet for Static, Direct, and BGP routing. If you are using Direct routing, this is the only subnet you need.
- A Peering subnet for Static and BGP routing.
For these subnets you can use:
- Provider-Assigned (PA) IP Addresses - Lease public IP Addresses owned by Equinix.
- Provider-Independent (PI) IP Addresses - Use public IP addresses that you own. (BYOIPs)
- Mixed IP Addresses - Use both your own and Equinix-owned public IP addresses.
Provider-Assigned IP Addresses
You can use Equinix-owned IPv4 and IPv6 addresses for your Internet Access service. The minimum size of the subnet depends on your routing configuration.
| Configuration | IPv4 subnet size | IPv6 subnet size |
|---|---|---|
| Single-Homed Direct | /30 | /64 |
| Single-Homed Static | /30 | /64 |
| Single-Homed BGP | /30 | /64 |
| Dual-Homed VRRP Direct | /29 | /64 |
| Dual-Homed VRRP Static | /29 | /64 |
| Dual-Homed BGP | 2 x /30 | 2 x /64 |
Provider-assigned (PA) IP addresses are non-portable and aren't announced through other providers unless connectivity is available to the Equinix-aggregated announcement. Initial Equinix assignments enable service interconnection between you and Equinix. You can't keep the address space after leaving the Equinix Internet Access transit platform.
Additional IP Address Space
Determine if you need more IP address space above the minimum for your use-case or routing configuration before ordering. The following subnet sizes are available:
- IPv4 subnets –
/30,/29,/28,/27,/26,/25,/24 - IPv6 subnets –
/64,/48
These addresses can be purchased as IPv4 only, IPv6 only, or as a dual stack where IPv4 and IPv6 are combined.
Additional IPs must be requested at the time of order. Requests for additional IPs after the order has been submitted require an new order.
Contact your Equinix representative for any regional differences. When you discontinue the services, these addresses are returned to the Equinix-owned pool of addresses.
Provider-Independent IP Addresses
Using Provider-independent (PI) IP addresses allows you to bring your own publicly routable IP addresses to use for your Internet Access routing.
If you choose to bring your own IP addresses, you must create the appropriate route objects and Route Origin Authorization (ROA) in an Internet Routing Registries (IRR) database to announce your IP address space with Equinix's ASN 15830.
If you are using BGP routing, Internet Access supports announcing your IP addresses from a private ASN, subject to your creation of valid route objects and Resource Public Key Infrastructure (RPKI) ROAs with Equinix 15830 as the origin. Use of a public ASN is only supported on Internet Access service on dedicated ports at this time.
Internet Access subnets require a minimum prefix size of /24 for IPv4 addresses or /48 for IPv6 addresses. To ensure global reachability, you must have one or more suitable route objects which exactly match their planned prefix announcements.
You can request IP address resources from these providers:
-
ARIN – American Registry for Internet Numbers, www.arin.net
-
RIPE – Réseaux IP Européens Network Coordination Centre, www.ripe.net
-
APNIC – Asia-Pacific Network Information Centre, www.apnic.net
-
LACNIC – Latin America and Caribbean Network Information Centre, www.lacnic.net
-
AFRINIC – African Network Information Center, www.afrinic.net
You can also request IP address resources from third-parties and announce any space you legitimately own.
After registering your subnet in an Internet Registry, you must wait 36 hours before attempting to create an Internet Access service. Approximately 36 hours are required to propagate information from a registry to Equinix.
Equinix cannot create RPKI ROAs for your subnets. These values must be created through the Regional or National Internet Registry where the prefix is currently registered.
Mixed IP Addresses
Internet Access supports using both Equinix-owned IP addresses and BYOIP on the same service. For example, if you want to use your own IP addresses for the peering subnet, but lease Equinix-owned IP addresses for the LAN subnet.
Using Mixed IP addresses are supported for the following routing configurations:
| Configuration | Internet Access Over Fabric | Internet Access Over Network Edge |
|---|---|---|
| Single Static Routing | Supported | Supported |
| Dual Static VRRP | Supported | NOT Supported |
| Single Direct Routing | NOT Supported | NOT Supported |
| Dual Direct VRRP | NOT Supported | NOT Supported |
| Single BGP | Supported | Supported |
| Dual BGP | Supported | Supported |
Mixed IP Addresses is not available on Internet Access over Dedicated Ports.
