Leaseweb BYOIP Integration Overview

This page outlines the technical and procedural information required for integrating Bring Your Own IP (BYOIP) with Leaseweb infrastructure. Leaseweb supports provider-announced BYOIP via its IP Announcement (IPAN) service, where your IPv4/IPv6 prefixes are originated from Leaseweb’s ASNs, and optionally Private AS BGP, where Leaseweb assigns you a private ASN for dynamic routing within your environment (while prefixes are still advertised from Leaseweb ASNs).

Tech Article & Date IPv4 address assignment and usage guidelines (IP Announcement summary) & IP Announcement and Private AS BGP.
BYOIP ScopeProvider-announced only: your IPv4/IPv6 prefixes are advertised from Leaseweb ASNs (IP Announcement). Announcing under your own public ASN is not supported.
Optional Private AS BGP gives you a private ASN and BGP session in private environments (racks / VMware), but prefixes are still originated by Leaseweb ASNs.
Supported VersionsIPv4 & IPv6 prefixes supported for IP Announcement (minimum /24 IPv4 and /48 IPv6 for external advertisement).
Supported Services IP Announcement (BYOIP) supported for: Dedicated Servers, Dedicated Racks, Colocation Racks, Elastic Compute, VMware Single Tenant vSphere & VMware HCI, VMware vCloud.
Not supported (per docs): Public Cloud, VPS, Shared Colocation units.

Technical Requirements

RequirementDetails
Prefix Size External announcement (IPAN): minimum /24 IPv4 and /48 IPv6 to be advertised to upstream providers.
Leaseweb prefers aggregated announcements; they can internally split space within the same data center down to approximately /26 IPv4 per rack for routing, while still advertising larger aggregates externally.
ASN Ownership Required Public ASN: not used for IP Announcement (prefixes are always originated from Leaseweb ASNs). Announcing under your own public ASN is not supported.
Private AS BGP: Leaseweb assigns you a private ASN (64512-65534) and establishes BGP sessions; full internet routing table is not provided (default route only).
IRR / Route Objects For IP Announcement, Leaseweb requires an accepted authorization method and correct IRR data:
- For RIPE space, delegate mnt-routes to Leaseweb’s maintainer so they can create route objects.
- For other RIRs/IRRs (ARIN, RADB, APNIC, etc.), ensure appropriate route records exist for the prefixes and the chosen Leaseweb location (NL, DE, US, UK, APAC).
ROA or LOA LOA: Required if the organization/person requesting IP Announcement does not directly own the prefix (Letter of Authorization from the RIR holder).
RPKI/ROA: Not strictly mandated in docs but strongly recommended to ensure global validation and to align with best practices.
RIR Limitations Prefixes must be properly registered with a major RIR (RIPE, ARIN, APNIC, etc.) and meet Leaseweb validation and policy requirements. No specific per-RIR exclusions are documented, but you must be able to create/adjust route objects and, where needed, delegate mnt-routes to Leaseweb.

Step-by-Step BYOIP Process

Estimated Setup Time:Not formally stated by Leaseweb; in practice, expect completion within a few business days after all route objects and LOA/authorization are in place (coordinate timelines with Leaseweb Support).Tested By Us:Not yet

A) IP Announcement (IPAN) - Leaseweb originates your prefixes

Step 1
Verify that your prefixes meet the requirements

at least /24 IPv4 or /48 IPv6, properly registered with RIPE/ARIN/APNIC, and with correct IRR route objects (e.g. mnt-routes delegated to Leaseweb for RIPE).

Step 2

Open a ticket via the Leaseweb Customer Portal or via your account manager, specifying the prefixes to be announced, the desired Leaseweb location(s) (NL, DE, US, UK, APAC), and the product(s) (Dedicated/Colo racks, Dedicated Servers, Elastic Compute, VMware).

Step 3
For racks/private environments

provide network design details (routers, default gateways, segmentation of larger blocks into /24s, redundancy), and clarify whether Leaseweb should handle rDNS for the space.

Step 4

If you are not the RIR holder of the prefixes, supply a Letter of Authorization (LOA) from the IP owner authorizing Leaseweb to announce the prefixes from its ASNs.

Step 5

Leaseweb validates ownership/IRR data, configures IP Announcement from the appropriate Leaseweb ASN(s), and attaches the blocks to your services (as rack-bound space or Floating IPs). Monitor global propagation using external BGP/route-view tools.

Step 6
Confirm that you use a private environment that supports Private AS BGP (Dedicated / Colocation racks or VMware Single Tenant vSphere / HCI).
Step 7
Request Private AS BGP via Leaseweb support.

Leaseweb assigns you a private ASN and configures BGP sessions from your rack/virtual edge towards its network (default route only; full table is out of scope).

Step 8

Optionally combine with IP Announcement so that your own prefixes are advertised under Leaseweb’s ASNs while you use BGP internally for routing and failover (subject to the same IPAN conditions).

Step 9

Implement BGP configuration on your routers/switches according to Leaseweb’s guidance, advertise your internal prefixes (up to the allowed number of subnets), and receive the default route from Leaseweb.

Step 10

Test traffic flows and failover paths, then monitor routing and performance over time (looking glasses, external route monitors, and Leaseweb Customer Portal graphs).

Cost and Limitations

ItemDetails
Fees IP Announcement: initial delivery includes announcement of up to 20 prefixes; additional announcement/de-announcement changes incur an Announcement Change fee per prefix as described in Leaseweb’s Service Specifications.
Any Leaseweb-provided IP addresses (if used alongside BYOIP) follow standard per-IP or per-subnet fees outlined in IPv4/IPv6 guidelines.
Bundled or Standalone IP Announcement is an add-on network service for: Dedicated servers, Dedicated Racks, Colocation Racks, Elastic Compute, VMware vSphere/HCI, VMware vCloud.
Private AS BGP is an add-on for private environments (Dedicated/Colo racks, VMware Single Tenant vSphere & HCI) and can be combined with IP Announcement.
Traffic/Peering Restrictions - All customer prefixes are announced only from Leaseweb ASNs; customer public ASNs cannot be used as origin.
- Minimum externally advertised sizes: /24 IPv4, /48 IPv6; smaller internal segmentation only within the same data center.
- Leaseweb prefers aggregated announcements and may review heavily de-aggregated plans on a case-by-case basis.
- Private AS BGP allows up to 100 subnets to be announced (combined IPv4/IPv6) from your private ASN towards Leaseweb.
Other Limitations - IP Announcement is not supported for Public Cloud, VPS, or Shared Colocation units.
- Private AS BGP is available only in private environments (full/half racks, VMware Single Tenant/HCI) and provides a default route, not a full internet table.
- Customer must operate BGP-capable network equipment and have internal networking expertise.
- Prefixes and usage are subject to Leaseweb’s Acceptable Use, spam, and abuse policies; ranges with serious reputation issues may require remediation.

Automation & Developer Access

  • API Access: Yes - Leaseweb Developer API (REST) and Customer Portal for managing servers, networking, and IPs. BYOIP/IP Announcement onboarding itself is typically initiated via support tickets or account management rather than self-service API.
  • CLI: Official "leaseweb-cli" command line interface for Leaseweb APIs (GitHub: Leaseweb organization).
  • Terraform: Official "terraform-provider-leaseweb" published by Leaseweb for managing infrastructure as code.
  • SDKs: Official Go SDK (leaseweb-go-sdk) and API definitions; additional community libraries available via GitHub and language ecosystems.

Abuse & Reputation Management

  • Leaseweb’s Compliance / Abuse Prevention department handles abuse notifications (spam, attacks, blocklists). Customers are expected to respond quickly via the ticket system and work with Leaseweb on remediation.
  • Customers remain responsible for monitoring the reputation of their announced prefixes and for following Leaseweb’s documented “Procedure to remove blacklist” and spam/abuse policies when delisting is required.
