IPv4 address assignment and usage guidelines

Description

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):

ServiceAll countries
Dedicated Server32
Virtual Server1
Shared Colocation16

Private / Colocated Rack

Half Rack

Full Rack


    128

    256

Private Cloud256


Note

Larger subnets are available on request. Our Sales team (sales@Leaseweb.com) will be happy to advise you on the next steps needed to request additional 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

Since each IP address is administratively assigned to a specific server, it is not possible to share or transfer addresses between servers. If you have your own internal network, it is possible to use a hardware firewall with NAT 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 services page in our self service center and select "IP" in the list on the left hand side, 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 in a shared environment.

IPv6

For information about Leaseweb's IPv6 network, please refer to the article on IPv4 address assignment and usage guidelines.

Ordering additional IP addresses

Please contact our sales department either by the Leaseweb Customer Portal, or by sending an email to sales@Leaseweb.com, and confirm the monthly fee. Specify the server and the desired amount of addresses, within the limitations explained above.

Please note that these fees are fixed and always excluded from any discounts.

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 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.


FAQs about IPv4 address

Can I run my own DHCP server in private network?

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 in a shared environment.

Can you please let me know 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 IP's on a rack or server (than the standard allocation of Leaseweb)and keep the IP's 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.
