## Recommended Actions

Based on risk assessment, the following firewall and security measures are recommended:

• iptables: `iptables -A INPUT -s 51.89.129.117 -j DROP`
• nftables: `nft add rule inet filter input ip saddr 51.89.129.117 drop`
• nginx: `deny 51.89.129.117;`
• pfSense: `51.89.129.117/32`
• Cloudflare WAF: Block IP 51.89.129.117 (expression: `ip.src eq 51.89.129.117`)
• AWS WAF: Add `51.89.129.117/32` to block rule set

## Intelligence Assessment

The IP demonstrates characteristics consistent with legitimate cloud hosting infrastructure. No active threat campaigns correlated with the address. However, the subnet's elevated abuse density warrants monitoring. Recommended action threshold remains at block-level filtering given the risk score of 40 and subnet abuse classification.
