iptables:
```
iptables -A INPUT -s 54.38.147.25 -j DROP
```
nftables:
```
nft add rule inet filter input ip saddr 54.38.147.25 drop
```
nginx:
```
deny 54.38.147.25;
```

## Intelligence Assessment
The target IP 54.38.147.25 operates as cloud hosting infrastructure within a high-abuse subnet (54.38.147.0/24). While no direct threat indicators are present, the 68.75% threat sibling ratio in the neighborhood warrants defensive consideration. The IP is associated with ahrefs.net infrastructure and maintains minimal operator risk. Monitoring recommendations suggest blocking at the perimeter due to the elevated neighborhood abuse density, though false positive mitigation should be implemented given the hosting infrastructure designation.
