Use clean IPv4 addresses on your network without buying them.
With a BRENAC lease, you rent a block of IPv4 addresses for the period you choose. We prepare the registry paperwork, check the block's reputation and give you the authorization to announce it. You pay a monthly fee, we keep ownership and you keep your capital. [Get a Lease Quote]
When you lease a block, you do not become its owner. The block stays registered to its holder, and you receive the right to use and announce it on your own network for the lease period. When the lease ends, the block returns to its holder and you stop announcing it.
| Lease | Buy | |
|---|---|---|
| Upfront cost | Small: first month's fee (TO CONFIRM: deposit) | The full price of the block |
| Monthly cost | Fixed lease fee | None |
| Ownership | Stays with the holder | Transfers to you |
| Time to start | (TO CONFIRM: delivery time, for example 1 to 3 business days) | Several weeks, because of the registry transfer |
| Flexibility | Add or return blocks as your needs change | The block is yours; resale takes a new transaction |
| Best for | Growth, projects, testing, short or uncertain needs | Long-term infrastructure you will keep for years |
If you plan to use the addresses for more than a few years, buying can cost less overall. We will compare both options for you at no charge. See Buy IPv4 Addresses.
| Item | What it is | Why you need it |
|---|---|---|
| Letter of Authorization (LOA) | A signed letter from the block's holder authorizing your ASN to announce the block | Upstream providers and internet exchanges ask for it before they accept your announcement |
| Route object | A record in the internet routing registry stating that your ASN may originate the block | Many providers filter announcements that have no route object |
| RPKI ROA | A cryptographic authorization checked by networks that reject unauthorized routes | Prevents your announcement from being dropped as invalid |
| Reverse DNS delegation | The right to set the name records for your addresses | Needed for email servers and many services |
| Reputation check | Blacklist, routing and geolocation audit before delivery | You start with a block that is ready to use |
| Support | A named contact for technical questions [to confirm: hours and channels] | Problems get fixed quickly |
Because BRENAC is a LIR, we create and update these records ourselves.

Leased addresses must be used lawfully and responsibly. Our acceptable use policy forbids spam, scanning, attacks, hosting of illegal content and any use that damages the reputation of the block.
You can lease it out through BRENAC and earn a monthly income while you keep ownership. We find and screen the lessee, prepare the contract and the authorization, manage the registry records and monitor the block's reputation. [to confirm: how the fee is calculated and when the owner is paid]
If you would rather sell it, see [Sell IPv4 Subnets].
Do I need my own ASN? Yes, to announce the block yourself. If you do not have one, tell us. [to confirm: whether BRENAC can announce the block for the lessee]
Can I use the addresses with a cloud or hosting provider? Yes, if the provider accepts bring-your-own-IP announcements and the authorization letter. We can supply what they ask for.
Are the addresses clean? We check every block against blacklists, routing history and geolocation before delivery. We cannot control what happens to a block after delivery, which is why the acceptable use policy exists.
Can I change the block size during the lease? Yes. You can add blocks or replace one with another, subject to availability. [to confirm]
What happens if I stop paying? [to confirm: payment grace period and suspension process.]
Can I buy the block I am leasing? [to confirm: whether lease payments count toward a purchase.] We can always quote a purchase price for the same block.
Which registries do you work with? RIPE NCC, ARIN, APNIC, AFRINIC and LACNIC. Availability by region is shown in the terms table above.
Tell us the block size, region and lease length, and you will receive a written quote with every term stated. [Get a Lease Quote]
