IP Reputation Management
How InterLIR Global monitors IP reputation and handles abuse for every block on the marketplace — for both Customers and Suppliers.
Blocks are scanned against major email and DNSBL blacklists before activation and throughout the lease period.
InterLIR Global maintains registered abuse contacts with RIRs and handles incoming complaints on behalf of Suppliers.
Suspicious usage patterns are detected early to prevent reputation damage before it escalates.
Every Customer and Supplier goes through identity and business verification before accessing the marketplace.
IP Reputation Management at InterLIR Global
Every IPv4 block listed on the InterLIR Global platform is subject to reputation checks and ongoing abuse monitoring. This protects both parties: Customers receive blocks that are clean and ready to route, while Suppliers protect the long-term value of their address space.
What Is IP Reputation?
IP reputation is the trust score of an address block based on its history of use. Blocks with a history of spam, phishing, or malware end up on blacklists — which reduces their deliverability, routing acceptance, and market value.
Clean IPs command higher lease and sale prices. Blocks with a compromised reputation require remediation before they can be used effectively.
What InterLIR Global Checks
Before a block is made available on the platform, and continuously during active leases, InterLIR Global runs the following checks:
- Email and DNSBL blacklists — major spam and abuse block lists
- RIR abuse history — whether the block has open abuse complaints at RIPE NCC, ARIN, APNIC, LACNIC, or AFRINIC
- Routing status — whether the block has conflicting route objects or active BGP announcements from other parties
- WHOIS accuracy — correct registration and contact information in the RIR database
When Checks Are Performed
| Stage | Check |
|---|---|
| Before listing | Supplier block is scanned before it becomes available |
| At activation | Block is verified clean before Customer receives the LOA |
| During lease | Periodic re-checks throughout the active lease period |
| On abuse report | Immediate investigation when a complaint is received |
How Abuse Incidents Are Handled
When an abuse report is received — from an RIR, a third-party blacklist operator, or any other source:
- The report is logged and the affected block is identified
- The Supplier and Customer are notified
- The nature of the abuse is investigated
- The Customer is given a remediation deadline
- If the issue is not resolved, the assignment can be suspended
- Repeat or severe abuse results in removal from the platform
InterLIR Global does not guarantee that all blocks are free of any reputation issues at all times. However, blocks with known unresolved issues are not listed as available.
What Customers Receive
Before receiving a LOA (Letter of Authorization), Customers are provided with:
- Blacklist check results at the time of activation
- Confirmation that the block has no open RIR abuse complaints
- Routing documentation for clean BGP announcement
Supplier Obligations
As a Supplier on the platform, you remain the RIR-registered holder of the address space. This means:
- Abuse reports from RIRs are addressed to you and must be handled promptly
- You are responsible for maintaining a valid abuse contact in the RIR database
- InterLIR Global acts as your operational point of contact for abuse handling during active leases
