Important Notice: IP Contract Expiration and RPKI Status – Ensuring Continuous Network Connectivity

Dear Valued Customer,

At LARUS, we are committed to providing reliable IP management services and ensuring the stability of your network operations. This notice is to inform you about crucial aspects of your IP resource contract, specifically concerning its expiration and the potential impact on your RPKI (Resource Public Key Infrastructure) status and network connectivity.

Understanding Your IP Contract and RPKI.

Your leased IP resources are governed by a service contract. Maintaining an active and valid contract is essential for the uninterrupted use of these resources and associated services, including RPKI.

RPKI is a security framework that validates the association between IP address blocks and the Autonomous Systems (ASNs) authorized to originate them. This helps prevent route hijacking and improves overall internet routing security.

What Happens if Your Contract Expires?

1. Contract Status Change: If your service contract for leased IP resources expires and is not renewed in a timely manner, its status will change to 'invalid'.

2. RPKI Dropped: Upon the contract becoming invalid, the RPKI records associated with your leased IP addresses will be dropped .

3. Network Impact: The dropping of RPKI records can have significant consequences for your network. It may lead to your IP prefixes being considered invalid by other networks, potentially resulting in offline status or severe network connectivity issues for services reliant on these IPs.

Restoring RPKI After Contract Invalidation

Should your contract lapse and your RPKI be dropped, the following steps are necessary to restore service:

1. Submit a Renewal Request: You must immediately contact our support team or your account manager to initiate the contract renewal process.

2. Complete Contract Renewal: Successfully renew your service contract for the IP resources.

3. RPKI Restoration Request: Once the contract is active again, a formal request for RPKI restoration must be made.

Important: RPKI Restoration Timeline

Please be aware that RPKI restoration is not instantaneous even after your contract is renewed. The process involves updates to routing registries and propagation across the internet.

- Standard Restoration Window: Typically, RPKI restoration may take [e.g., 24-72 business hours] after your renewed contract is fully processed and the RPKI restoration request has been confirmed by our team.

- Factors Affecting Timeline: This timeframe can be influenced by external registry update cycles and global BGP propagation times.

We strongly advise you to plan accordingly to minimize any potential service disruption.

Proactive Measures to Avoid Service Disruption

To ensure continuous service and avoid the complexities of RPKI restoration, we highly recommend:

- Monitoring Expiration Dates: Keep track of your IP contract expiration dates.

- Timely Renewal: Initiate the renewal process well in advance of the expiration date (e.g., at least 30-60 days prior).

- Maintain Communication: Ensure your contact information with us is up-to-date so you receive renewal notices and important communications.

Your network stability is our priority. We encourage you to manage your IP contracts proactively. If you have any questions regarding your contract status, renewal process, or RPKI, please do not hesitate to contact our support team at [Support Email Address] or [Support Phone Number].

Thank you for your attention to this important matter.

Sincerely,

LARUS
