IPv4 address assignment and usage guidelines

This article provides information about IPv4 Address Assignment and Usage Guidelines.

IP addresses are allocated to Leaseweb by the Regional Internet Registries (RIRs) such as RIPE, ARIN and APNIC. In turn, Leaseweb assigns those IP addresses to its customers for use while the customers are connected to the Leaseweb network. IP addresses are assigned abiding the RIPE/ARIN/APNIC policies and in line with RFC2050.

IP address limitations

Due to the depletion of the pool of unallocated IPv4 addresses (IPv4 address exhaustion), Leaseweb cannot get new IP addresses from RIRs. Therefore, the maximum number of IP addresses that can be assigned to customers per service type is limited (shown in the table below):

* Our Sales team will be happy to advise you on the next steps needed to request larger subnets of IPs.

The IP’s for Dedicated Servers, Virtual Servers (VPS) and Shared Colocation Units are delivered as individual IPv4’s. Dedicated Racks, Colocation Racks and Private Clouds get a single IPv4 subnet assigned.

Information

Larger subnets are available on request. Our Sales team will be happy to advise you on the next steps needed to request larger subnets of IPs.

One IP address is automatically configured on the server. Extra IP addresses assigned still need to be configured on the server by the customer. 

Sharing IP addresses between servers

Since each IP address is administratively assigned to a specific server, it is not possible to share or transfer addresses between servers. If you use Leaseweb Private Network or have your own internal network, it is possible to use a hardware firewall with NAT (Network Address Translation) to reduce the amount of public IP addresses needed.

Warning

It is not allowed to configure an IP address on your server that is not assigned to it. Doing so will result in suspension of your server.
Please go to the My account > All Products page in your customer portal and select IP to see an overview of the IP addresses available for your servers.

DHCP

DHCP is not used within the Leaseweb network except under special circumstances, and is not offered by Leaseweb as a service. You are not allowed to run your own DHCP server on the public network in a shared environment.

IPv6

Leaseweb can provide IPv6 IP addresses to your environment.
For information about Leaseweb’s IPv6 network, please refer to the article on IPv6 address assignment and usage guidelines.

Ordering additional IP addresses

For Dedicated Server, Dedicated Racks and Colocation racks, additional IP addresses or subnets can be ordered through the customer portal, using the Request more IPv4 Adresses link under the Actions menu on the product’s detail page.

Monthly fee

LocationCost per
month (IPv4)		Cost per
month (IPv6)
NL & DE€2,70 / IPFree
US$3,70 / IPFree
SGS$5,70 / IPFree

Information

  • Fees are fixed and always excluded from any discounts.
  • When a subnet is assigned, 5 of the IP addresses from the subnet are not usable (the network, two router, gateway and broadcast addresses). The fee is applied to all addresses in the subnet.

Canceling additional IP addresses

Canceling additional IP addresses is also possible from the Customer Portal.

For Dedicated Servers in Shared racks and shared Colocation, you can click the 16744516 icon next to any additional IP address on the IP Addresses page under the Details menu to cancel it

IP Announcement

Leaseweb can announce your IP addresses within its network. To be able to announce your IP addresses, we need an accepted authorization method. For example, for RIPE ranges, we need you to delegate “mnt-routes” to Leaseweb.

IP Announcement of Customer provided prefixes is supported from Leaseweb ASNs. The minimum range to be announced is a /24. We do allow splitting IP space across the network in the same data center to as small as /26 per rack.

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.

IPv4 address assignment and usage guidelines - Frequently Asked Questions

  • Can I run my own DHCP server in private network?

    Yes, you can. However, it is necessary to disable Leaseweb’s DHCP server first. This can be done via the DHCP Reservations toggle switch at the top right of the Private Network page in the Customer Portal:

     

    Note: Disabling the DHCP server also turns the private network into a pure Layer 2 network. Any other services provided on the Private Network will no longer be available.

     

     

  • Can I manage DHCP private network reservations?

    Yes, you can. Besides having an overview or list of the active reservation, you also have the possibility to reserve a specific IP address for a client or remove it.

    This can be done via the DHCP Reservations toggle switch (Edit) at the top right of the Private Network page in the Customer Portal:

    Once the wizard is opened you can choose to create a DHCP reservation by entering a valid format of a MAC address of compute resources in your private network and IP address from the designated subnet.

    You can also choose to remove an existing reservation or make it stick after the renewal process by selecting the ‘Sticky’ option.

     

    Note: If you wish to update an active DHCP reservation, you have to re-create by removing and adding it again.

     

     

  • What is IP Announcement?

    IP Announcement (IPAN) enables customers who have their own IP Ranges to announce their IP addresses by Leaseweb.

    This allows customers to use a larger amount of IPs on a rack or server (than the standard allocation of Leaseweb) and keep the IPs when moving to another provider. The IPAN service is only available for complete racks.

    IP Announcement is supported only in Leaseweb ASNs. The minimum range to be announced is a /24. We do allow splitting IP space across the network in the same data center to as small as /26 per rack. 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.
