🔍 IP Reputation & Blacklist Lookup Tools
How can I check the details or reputation for an IP address?
To check if an IP address is blacklisted or flagged for poor reputation, you can use trusted third-party tools like:
✅ 1. MXToolbox Blacklist Check
MXToolbox is a highly trusted tool for checking if an IP is listed in over 100 DNS-based blacklists (DNSBLs). It also provides insights for:
- IP reputation
- Email delivery issues
- SMTP diagnostics
How to use:
- Visit: https://mxtoolbox.com/blacklists.aspx
- Enter the IP address (or domain) you want to check.
- Click Blacklist Check.
- Review the results to see if your IP is listed on any blacklist.
✅ 2. UCEPROTECT Network
UCEPROTECT focuses on real-time abuse detection and lists IPs at multiple levels (L1, L2, L3) based on their behavior.
How to use:
- Go to: http://www.uceprotect.net/rblcheck.php
- Enter the IP address.
- Submit and check if your IP is listed in UCEPROTECT’s blacklist levels.
