Leasing rates are set by the owner of each block and shown on the listing. Everything below is what IPv4 Hub itself charges — which is nothing until a lease is actually running.
Each listing shows a monthly price set by the block's owner. That is the whole cost. There is no platform fee, no per-address surcharge and no charge for authorisation or routing objects.

Listing costs nothing and carries no obligation. IPv4 Hub takes a commission on the monthly lease value once a block is actually leased and the tenant has paid.

On a /24 letting at $130 a month you receive $110.50 and IPv4 Hub receives $19.50.
Monitoring of a block you lease through IPv4 Hub is included for both parties. These prices are for monitoring your own address space independently — useful whether or not any of it is listed here.
Price depends on two things: how large the block is, and how often you want it checked. A /24 checked twice a day is the entry point.
One monitor, up to a /24, checked daily. Enough to see the block map, the per-blocklist breakdown and an alert email.
A /24 — 256 addresses — checked every 12 hours, with email alerts on any new listing.
Blocks from a /24 to a /12, at check frequencies from daily down to every two hours. Full table below.
A sample of the matrix at three check frequencies. Every size from /24 to /12 and every frequency from 24-hourly to 2-hourly is priced — the full table is on the billing page.
| Block | Addresses | Daily | Every 12 hours | Every 2 hours |
|---|---|---|---|---|
| /24 | 256 | — | $9.99 | — |
| /23 | 512 | — | $19.99 | — |
| /21 | 2,048 | $19.99 | $117.99 | $199.99 |
| /20 | 4,096 | $29.99 | $176.99 | $299.99 |
| /19 | 8,192 | $49.99 | $294.99 | $499.99 |
| /16 | 65,536 | $249.99 | $1,476.99 | $2,499.99 |
Checking more often costs more because it is more queries against the blocklist providers, and those providers cap how much any one organisation may ask. That cap is the real constraint, which is why price scales with frequency rather than being flat per block.
RepRadar checks against 25 live DNS blocklists. UCEPROTECT levels 2 and 3 list whole netblocks and autonomous systems rather than individual addresses, so they are reported for context but never counted toward a clean-or-listed verdict.
No. There is no listing fee, no setup fee and no charge for the Letter of Authorization, ROA or IRR object. Tenants pay the monthly lease rate; owners pay a commission only on money actually collected.
IPv4 Hub takes 15% of the monthly lease value from the owner. The tenant pays the listed price and nothing on top — the rate you see on a listing is the rate you pay.
Blacklist monitoring of the block you are leasing is included for the life of the lease, for both parties. Paid RepRadar plans are for monitoring space you already hold, whether or not it is leased through us.
Because each check is a real query against every blocklist provider, and those providers cap how much any one organisation may ask per day. Frequency is what consumes that budget, so it is what the price scales with.
Yes, at any time from the billing page. It runs to the end of the period you have paid for and then stops. There is no cancellation fee.
Most people arrive needing addresses. Some arrive holding them. Both are welcome.
