- Consider blocking at firewall level (iptables/CSF) to reduce server load
- Other malicious IPs detected in the same /24 subnet — consider blocking 16.52.51.0/24
- Report abuse to the network provider via their abuse contact
- Ensure sensitive files (.env, .git, backups) are not accessible from the web

Security Intelligence
💡 DDoS Mitigation Approaches
Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.
💡 BGP Hijacking and IP Spoofing
Border Gateway Protocol hijacking allows attackers to redirect internet traffic through their infrastructure. While less common than application-level attacks, BGP hijacks can intercept sensitive data, inject malware, or cause widespread service disruption.
