IP Announcement (IPAN) enables you (if you have your own AS (Autonomous System) and IP Ranges) to have your IP addresses announced by Leaseweb. This allows you to use a larger amount of IPs on a rack or server (than the standard allocation limit of Leaseweb) and keep the IPs when moving to another provider.
Both IPv4 and IPv6 prefixes are supported for IP Announcement.
Leaseweb doesn’t impose a limit to the maximum number of prefixes that can be announced but does have rules in place to keep it manageable.
The announced IP addresses will be advertised from a Leaseweb AS number. The IP prefix size needs to be greater than or equal to a /24 IPv4 or /48 IPv6 in order for us to advertise the prefix to our upstream providers. To be able to announce your IP ranges, we need an accepted authorization method. For example, for RIPE ranges, we need you to delegate “mnt-routes” to Leaseweb.
Information
IP announcement is only available out of the Leaseweb ASNs, using the customer’s own ASN is not available.
If the organization and/or individual does not own the IP prefix that needs to be advertised, we will require a Letter Of Authorization (LOA) from the actual owner of the IP prefix. There are no limits set for the amount of announced prefixes. Leaseweb prefers to aggregate the announced prefixes as much as possible. However, there are scenarios when this may differ and Leaseweb can look at per case if there is a valid technical reason.
The initial delivery of the IPAN service includes the announcement of a maximum of 20 prefixes. Any prefixes that are requested to be announced or de-announced beyond the initial 20 prefixes or after the initial delivery has been completed, will be handled as an Announcement or De-Announcement request, for which an Announcement Fee per prefix is applicable.
The IP Announcement service is available in the following Leaseweb services:
- Dedicated servers
- Dedicated racks
- Colocation racks
- Elastic Compute
- VMware Single Tenant vSphere and VMware HCI
- VMware vCloud
IP Announcement for Dedicated servers in Dedicated racks and Colocation racks
For Dedicated servers in Dedicated racks and Colocation racks, we announce the IP addresses from our network. The IP addresses will be advertised from a Leaseweb AS number and, they are available to be used in the racks (Dedicated or Colocation) that you have.
The minimum subnet that we can announce is /24 IPv4 and/48 IPv6. We do allow splitting IP space across the network in the same Data Center to as small as /26 IPv4 per rack.
How IP Announcement works for Dedicated servers in Dedicated racks and Colocation
In order to proceed with the IP Announcement service, we need the following information:
- What is/are the prefix(es) you want us to announce?
- In case of /23 (IPv4) and bigger, do you want the IP range in one large subnet or divided up in multiple /24 subnets? (we will aggregate the announcement to the Internet, and do not permit de-aggregation)
- Which IP addresses do you prefer for router and default gateway addresses? (i.e. .252 for rtr1, .253 for rtr2 and .254 for def. gw. , preferable to the last addresses in the subnet)
- Please provide us with a complete description of the network setup
- Do you want Leaseweb also to announce the rDNS records? Please announce our authoritative nameservers in the address space. See https://kb.leaseweb.com/support/cheat-sheet
- Depending on which location you want us to announce the prefix(es) (NL, DE, US, UK, or APAC), route records need to be created with the appropriate registry (RIPE, ARIN, RADB, APNIC, etc.). Please let us know the original registry that assigned the prefix(es) and from which Leaseweb location you would want us to announce the prefix(es)
Once we have the above information and if needed a Letter Of Authorization (LOA) from the actual owner of the IP prefix, we can proceed with the steps to announce the IP addresses.
The IP addresses will be registered under the Dedicated rack or Colocation service (half/full racks), and you can find them under these services in the Leaseweb Customer Portal.
IP Announcement for Dedicated servers in Shared racks
For Dedicated servers in Shared racks, we announce the IP addresses from our network. The IP address will be advertised from a Leaseweb AS number and they are available to be used on any Dedicated server in a shared rack.
The minimum subnet that we can announce is /24 IPv4.
How IP Announcement works for Dedicated Servers in Shared racks
In order to proceed with the IP announcement service, we need the following information:
- What is/are the prefix(es) you want us to announce?
- Do you want Leaseweb also to announce the rDNS records? Please announce our authoritative nameservers in the address space. See https://kb.leaseweb.com/support/cheat-sheet
- Depending on which location you want us to announce the prefix(es) (NL, DE, US, UK, or APAC), route records need to be created with the appropriate registry (RIPE, ARIN, RADB, APNIC, etc.). Please let us know the original registry that assigned the prefix(es) and from which Leaseweb location you would want us to announce the prefix(es)
Once we have the above information and if needed a Letter Of Authorization (LOA) from the actual owner of the IP prefix, we can proceed with the steps to announce the IP addresses.
The IP addresses will be registered as Floating IPs in our systems and can be found in the Leaseweb Customer Portal in the Floating IPs section.
Tip
From the Floating IP section, you can create Floating IP definitions (static routes) to route traffic from your IP addresses to Leaseweb IP addresses.
You can find instructions on how to create Floating IP definitions here.
Private AS BGP
Definitions
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP learns and exchanges path information regarding the route to a given destination network by keeping lists of AS numbers and associating them with destination networks. This is why AS numbers should be unique. BGP makes certain that an AS number does not appear in a path more than once, thereby preventing routing loops.
An autonomous system (AS) is a connected group of one or more IP prefixes run by one or more network operators which have a SINGLE and CLEARLY DEFINED routing policy. (RFC1930) The AS must be globally unique so that IP address blocks appear to come from a unique location that BGP can find and route to. BGP uses Prefixes and Autonomous System Paths (AS Paths) to determine the shortest path to a destination where a prefix is located.
Description
Private AS BGP is a service to which we assign a Private AS Number (64.512 – 65.534) and we enable BGP sessions with our network. A customer will have a default route, the full routing table is not in scope. BGP capable switches and knowledge of how to manage BGP are required.
Private AS BGP is only available in private environments (e.g. full rack colocation). It can be combined with IP Announcement to have full control over the announcement.
IP Announcement conditions and requirements apply if it is combined with Private AS BGP.
Private AS BGP is also available in combination with Leaseweb IP addresses. With Leaseweb addresses, the IP subnet can be less than /24, if it is used in racks within the same Leaseweb Data Center.
If Leaseweb IP addresses will be used in racks in two Data Centers within the same metro area, then the minimum subnet that we can assign is /24.
The maximum number of subnets that can be announced with Private AS BGP is 100.
