Legal

Acceptable Use.

Last updated 9 September 2026.

Draft pending legal review. The prohibitions below reflect how we intend to operate and have not yet been reviewed by counsel.

Why this policy exists

An Owner leasing you space is lending you their reputation. Addresses that get blocklisted stay blocklisted after your lease ends, and the damage lands on the person whose name is on the registration. This policy is what makes it reasonable for Owners to lease at all.

Prohibited outright

  • Sending unsolicited bulk email, or providing any service to those who do.
  • Operating open relays, open proxies or open recursive resolvers.
  • Phishing, credential harvesting, or hosting content designed to impersonate another organisation.
  • Distributing malware, operating command-and-control infrastructure, or hosting exploit kits.
  • Launching denial-of-service attacks, or providing infrastructure for them.
  • Port scanning, vulnerability scanning or intrusion attempts against networks that have not authorised it.
  • Announcing address space you are not authorised to announce, or originating routes for prefixes not covered by your lease.
  • Child sexual abuse material, or content that is unlawful in the jurisdiction from which it is served.
  • Sub-leasing, reselling or transferring the right to announce without the Owner's written consent.
  • Falsifying registry records, WHOIS data or abuse contact information.

Conditions on email

Sending email from leased space is permitted where the Owner's listing allows it. If you do, you must use verified opt-in for bulk sending, honour unsubscribe requests promptly, publish accurate SPF and DKIM records, maintain a working abuse@ address, and keep complaint rates low. Repeated blocklist entries are treated as a breach even where each individual listing is later removed.

Your responsibilities as a Tenant

  • Maintain a monitored abuse contact and respond to reports within one business day.
  • Keep accurate records of who is using the addresses if you reassign them onward.
  • Register reassignments where your registry requires it.
  • Act on blacklist alerts rather than waiting for the listing to expire.

Reporting abuse

Send reports to abuse@ipv4hub.net with the IP address, timestamps including timezone, and enough log detail to identify the activity. We acknowledge reports within one business day and pass them to the Tenant and Owner.

What happens on a breach

Depending on severity: a notice with a window to remediate; suspension of the route authorisation; or immediate termination of the lease and revocation of routing objects. Serious abuse — malware distribution, denial-of-service, illegal content — results in immediate termination without a remediation window. Owners are informed at every step, and we cooperate with law enforcement where legally required.

Appeals

If you believe action was taken in error, write to info@ipv4hub.net with the details. We will review and respond within five business days.
