# nftables

nft add rule inet filter input ip saddr 20.206.87.81 drop

# nginx

deny 20.206.87.81;

# pfSense

20.206.87.81/32

# Cloudflare WAF

ip.src eq 20.206.87.81 → BLOCK

# AWS WAF

Addresses: ["20.206.87.81/32"]

```

Operational Note: IPDebrief recommends these actions as probabilistic measures. Integration with additional threat intelligence signals and organizational context is advised before implementing blocking rules.

## THREAT INTELLIGENCE CONCLUSION

IP 20.206.87.81 represents Microsoft Azure cloud infrastructure with moderate risk scoring. The absence of open services, clean neighborhood classification, and zero threat persistence days indicates this is legitimate infrastructure rather than actively malicious. However, the DNSBL listings and moderate risk score warrant continued monitoring.

Recommended SOC Action: Monitor traffic patterns; implement rate limiting or connection restrictions rather than outright blocking, pending correlation with organizational threat data.
