What is an IP Leasing Contract?
An IP leasing contract gives your business the use of an address block for an agreed period. For an ISP, hosting provider or cloud operator, the real value is usable capacity, room to grow and continuity for the customers already relying on your network.
Explore IPv4 ContinuityWhat does an IP leasing contract cover?
It connects a defined block of Internet Protocol addresses to your deployment: which addresses you can use, when service starts, how billing works and how you renew. The practical result is public IPv4 capacity for your servers, subscribers or cloud services without buying a block upfront.
A useful agreement also makes the operating relationship clear. Your team needs to know who prepares routing authorization, maintains registration information and resolves an issue when a customer is waiting. Those details turn address supply into a service you can build on.
Why lease IPv4 instead of buying?
Leasing keeps more capital available for the parts of your business that win customers: network reach, servers, support and new locations. You can plan capacity around demand instead of financing a large purchase before that demand arrives.
Buying does not remove the registry relationship. A transfer changes the registered holder; it does not make the address block independent of registry services. ARIN's Registration Services Agreement, for example, describes contractual registration and use rights. The commercial question is who carries that upstream relationship while you run your network.
LARUS supplies IPv4 directly from the pool it operates. Its Continuity proposition brings the registry-facing work upstream to LARUS, so your team can concentrate on keeping customers connected. Heng Lu explains the registry-risk foundation behind this approach.
How does an IP lease become working capacity?
- Start with your rollout. Bring the block size, deployment location, ASN and target date. That gives the supply team the information needed to match the addresses to your network.
- Agree the commercial plan. Connect the lease period, billing and renewal to your customer commitments and expansion plans.
- Prepare the route. Coordinate the letter of authorization, routing records and RPKI/ROA settings for your announcement. These give upstream networks the information needed to recognize your route.
- Launch and build ahead. Check reachability, put the addresses to work and plan additional capacity before the next customer rollout.
Which lease structure fits your network?
A project lease fits a defined deployment or temporary capacity requirement. A longer-term arrangement fits services that depend on stable addressing and an orderly renewal plan. The right choice follows the lifetime of the service you are selling.
Also look at the supply chain. A broker can introduce a provider; a sublease adds another party between your business and the resource holder. Direct first-party supply gives you a clearer relationship with the operator delivering the addresses. With LARUS, the conversation is about your network's capacity and continuity, rather than finding another listing.
What keeps the service dependable?
Once customers depend on an IP address, replacing it can mean changing DNS, access lists, integrations and deployment schedules. Compare providers on the work behind the block: renewal planning, routing support, incident handling and the registry relationship.
Ask practical questions: can your network announce the block as planned? Who helps if an upstream rejects a route? How is an expansion coordinated? A clear operating contact and a supply plan matter long after the first invoice.
Plan for growth while IPv6 develops
IPv6 adoption and today's IPv4 demand can be part of the same plan. Keep the IPv4 capacity your existing customers and applications need while developing IPv6 on your own timetable. Leasing lets you direct investment toward that rollout instead of making every growth decision an address purchase.
LARUS IPv4 Continuity brings Unlimited IPv4 and a continuity-led supply relationship to operators building for their next stage of growth.
IP leasing contract questions
Can I renew an IP lease?
Renewal is part of the supply plan. Agree the term and renewal arrangements around how long your customers will need the addresses, so your team can plan ahead instead of reorganizing a live service at the last minute.
Can I use leased addresses with my own ASN?
Yes, a lease can support an announcement from your ASN. Routing authorization and upstream coordination connect the block to your network; share your ASN and deployment plan when discussing supply.
Who handles the registry relationship?
The registered holder maintains the upstream registry relationship. LARUS's first-party model places that work with the address supplier, alongside the continuity service supporting your business.
Is a broker the same as a continuity provider?
No. An introduction helps you find addresses. Continuity addresses what happens after they are in service: the supply relationship, operational support and the upstream structure your business relies on. That is the difference to explore when choosing LARUS.
