Usage Examples - Blocking IBM Cloud IPs

Download the IP ranges

# Download with curl
curl -O https://cloud-ip-ranges.com/download/ibm-cloud.txt

# Or download with wget
wget https://cloud-ip-ranges.com/download/ibm-cloud.txt

Block with iptables (Linux firewall)

# Download and block IBM Cloud IPs with iptables
wget -O ibm-cloud_ips.txt https://cloud-ip-ranges.com/download/ibm-cloud.txt
while read ip; do
  iptables -A INPUT -s $ip -j DROP
  iptables -A OUTPUT -d $ip -j DROP
done < ibm-cloud_ips.txt

Block with UFW (Ubuntu/Debian firewall)

# Download and block IBM Cloud IPs with UFW
wget -O ibm-cloud_ips.txt https://cloud-ip-ranges.com/download/ibm-cloud.txt
while read ip; do
  ufw deny from $ip
  ufw deny to $ip
done < ibm-cloud_ips.txt

Block with fail2ban (intrusion prevention)

# Create fail2ban filter for IBM Cloud
sudo tee /etc/fail2ban/filter.d/ibm-cloud-block.conf << EOF
[Definition]
failregex = ^.*$
ignoreregex =
EOF

# Create jail configuration
sudo tee /etc/fail2ban/jail.d/ibm-cloud-block.conf << EOF
[ibm-cloud-block]
enabled = true
filter = ibm-cloud-block
action = iptables-allports[name=ibm-cloud]
logpath = /tmp/ibm-cloud_ips.txt
findtime = 1
bantime = -1
maxretry = 1
EOF

# Download IP list and restart fail2ban
wget -O /tmp/ibm-cloud_ips.txt https://cloud-ip-ranges.com/download/ibm-cloud.txt
sudo systemctl restart fail2ban

Block with pfSense/OPNsense (FreeBSD firewall)

# Create alias table for IBM Cloud IPs
# 1. Download the IP list
wget -O ibm-cloud_ips.txt https://cloud-ip-ranges.com/download/ibm-cloud.txt

# 2. In pfSense/OPNsense web interface:
# - Go to Firewall > Aliases
# - Create new alias named "IBM-CLOUD_BLOCK"
# - Type: Network(s)
# - Import the downloaded file
#
# 3. Create firewall rule:
# - Go to Firewall > Rules > WAN
# - Add rule: Action=Block, Source=IBM-CLOUD_BLOCK
