Introduction

This document (“Policy”) sets out Modica’s policy for assigning IP address space to customers and the obligations of the customer who uses IP addresses assigned by Modica, or has accepted the terms and conditions of this Policy by agreeing to a related Service Description (the “Customer”). In this policy we refer to APNIC (Asia Pacific Network Information Centre). APNIC is an open, membership-based, not-for-profit organization. It is one of five Regional Internet Registries (RIRs) charged with ensuring the fair distribution and responsible management of IP addresses and related resources. These resources are required for the stable and reliable operation of the global Internet. This responsibility is delegated to APNIC by ICANN (Internet Corporation for Assigned Names and Numbers).

IP addresses are not owned by the Customer or Modica, but are managed by APNIC Pty Ltd (“APNIC”) which allocates address space to Modica and its suppliers in its capacity as a custodian of that allocation. This policy details the conditions under which Modica and its suppliers will sub allocate their assignments from APNIC. Modica and its suppliers must adhere to the APNIC member policies posted at: http://www.apnic.net/policy/add-manage-policy and http://www.apnic.net/policy/ipv6-address-policy The Customer must comply with all such policies that apply to it, and must ensure that it is not responsible for Modica or its suppliers failing to comply with such policies.

IP Addresses – number of addresses per prefix length

The following table sets out the prefix lengths of IP addresses that Modica may assign to the Customer depending on the Customer’s requirements, and the number of addresses and useable addresses associated with each prefix length. The number of usable addresses is always two fewer than the total number of addresses for the prefix. This is because the network address (all zeroes) and the broadcast address (all ones) cannot be used for addressing purposes.

/464.8 x 1024  

(1) This prefix length is generally only used for host routes.  (2) A /31 prefix length is not used by Modica.  (3) IPv6 by design uses very large numbers 

Modica retain administrative control of address space

IP addresses assigned by Modica to the Customer remain under the administrative control of Modica and can therefore be revoked, changed, or re-assigned at Modica’s sole discretion outside of the term of this agreement. Further, APNIC may ask Modica to hand back address space. In such cases, where such address space has been assigned to the Customers, the Customer must promptly return it to Modica.

All /29 assignments or larger must be registered with the APNIC Whois database

All assignments of size /29 or larger must be registered with the APNIC Whois database. Modica will register these assignments and provide Customer information relating to that assignment to APNIC. APNIC may publish such Customer information on the Whois database. The Customer must ensure that such information it gives to Modica is kept up to date so that the information Modica provides to APNIC is up to date.

IP address assignment requires Modica Internet product

Only Customers who purchase internet services from Modica are allowed to receive an IP address assignment from Modica. This is an APNIC policy requirement.

Termination of Internet services

If the Agreement for the provision of Internet services between Modica and the Customer is terminated for any reason, the Customer must return the address space immediately to Modica, and Modica will cease to route and advertise the IP address on behalf of the Customer. Under no circumstance will the Customer be allowed to retain the address space after termination of internet services. This is an APNIC policy requirement.

Charging for IP address space

The APNIC member policies prohibit Modica from charging the Customer for IP addresses themselves. However, Modica may charge the Customer for services related to managing the assignment and international advertisement.

Assignment of IPv4 Address Space

All assignment requests must follow the standard service order process:

/29 block can be allocated without justification

A Customer can be allocated a /29 or smaller without written justification of their requirement for IP address space. However, if the Customer already has one or more assignments, these will be taken into account. In other words, the size of all assignments made to the Customer will be factored in. For example, if the Customer has a /29 and requests another /29, a written justification is required, since that Customer would have a total of a /28 should the assignment be approved.

/27 or larger assignments require justification

The Customer must provide a written justification of how the address space is to be used for all assignments of size /26 or larger. The justification must include a network diagram.

/24 or larger - second opinion request

Any allocation request of size /24 or larger must initiate a second opinion request to APNIC. Modica or its suppliers will apply to APNIC on behalf of the Customer, assuming Modica agrees with it also. If APNIC turns down the second opinion request, the assignment will not be made to the Customer. This is beyond the control of Modica.

/23 or larger - Customer should get address space from APNIC

Customers having or requesting a total of a /23 (or larger) assignment may be able to get portable address space directly from APNIC. Customers are strongly encouraged to do so. e.g. /22 or larger: Customer must get address space from APNIC Customers having or requesting a total of a /22 (or larger) assignment must get portable address space directly from APNIC.

Assignment of IPv6 Address Space

All assignment requests must follow the standard service order process:

/48 block can be allocated without justification

A Customer can be allocated a /48 or smaller without written justification of their requirement for IP address space. However, if the Customer already has one or more assignments, these will be taken into account. In other words, the size of all assignments made to the Customer will be factored in.

/47 or larger - second opinion request

Any allocation request of size /47 or larger must initiate a second opinion request to APNIC. Modica will apply to APNIC on behalf of the Customer, assuming Modica agrees with it also. If APNIC turns down the second opinion request, the assignment will not be made to the Customer. This is beyond the control of Modica.

Common Policies

Route aggregation

Where a Customer requests an initial (IPv4) /29 (or other size) assignment and then later asks for another (IPv4) /29 (or other size), Modica may choose to revoke the initial assignment and issue one contiguous (IPv4) /28 assignment. This is to maximise the opportunity to aggregate routes. Should this happen, the Customer is required to return the relevant address space and have new address space assigned by Modica.

Contiguous address space assignment

Modica may choose to not assign contiguous address space when a Customer with a current assignment requests further address space. In other words, Modica cannot guarantee that a Customer receives contiguous address space when provided with multiple assignments. As a matter of fact, most Customers today having multiple assignments do have discontiguous ones.

Customer specific reverse DNS records

Customers can request specific reverse DNS records for their assignments. For example, a Customer may want to have the forward and reverse DNS records for their mail server match.

Reverse DNS delegation (for (IPv4) /24 or larger, (IPv6) /64 or larger)

Customers can request the reverse delegation for assigned (IPv4) /24 and/or IPv6 /64 blocks to point to the Customer’s name servers.

Multi-homed Customers must use portable address space

Customers that are multi-homed must apply for portable address space directly from APNIC. . To do this, the Customer can apply for a membership from APNIC.

AS Numbers

Customers that require a public ASN (autonomous system number) are usually multi-homed, or about to become multi-homed. In this case, they should refer to the above paragraph relating to multi-homed Customers.

Modica will never assign more than an IPv4 /23 to Customers (512 addresses)

Customers requiring a larger assignment than an IPv4 /23 must apply for address space directly from APNIC.

Modica will never assign more than a IPv6 /46 to Customers (4.83570328 × 1024 Addresses)

Even though Modica adds both forward and reverse DNS records for all assignments, Customers can (of course) add their own forward records pointing to addresses within their assignment. These DNS records and zones can be managed by the Customer itself or by the Customer purchasing a Modica product, such as DNS.
