iptables -A INPUT -s 103.127.0.151 -j DROP

# nftables

nft add rule inet filter input ip saddr 103.127.0.151 drop

```

WAF Configuration

```nginx

# nginx

deny 103.127.0.151;

# Cloudflare WAF

{"description":"Block 103.127.0.151 — IPDebrief risk score 40","action":"block","filter":{"expression":"ip.src eq 103.127.0.151"}}

# AWS WAF

{"Addresses":["103.127.0.151/32"],"Description":"IPDebrief risk 40"}

```

## Operational Notes

1. Block with Caution: While listed on DNSBLs with "high" severity, the IP shows no active services or behavioral indicators of active exploitation

2. Monitor Neighborhood: Three neighboring IPs in the /24 show medium risk; consider evaluating subnet-wide policies

3. Geographic Context: Infrastructure located in Bangladesh may warrant enhanced monitoring depending on organizational threat landscape

4. No Immediate Threat: IP is not identified as active attacker, spam source, or known malicious campaign participant
