+## How To Block Any IP Address In MAC
+
+The easiest way to block IP addresses on a Mac is to block them for your entire network via your router. If you want to block an IP address on just your Mac, use the Terminal to create a new rule in your PacketFilter Configuration file.
+
+1. Find the IP address you want to block from the list found here: https://github.com/Summer-CMS-Vendor-Packages/sc-block-bad-crypto-filter-lists/blob/master/src/lists/ip.txt
+
+2. [Open Terminal](#) and enter the following to open the PacketFilter Configuration file:
+
+```
+$ sudo vim /etc/pf.conf
+```
+
+3. Enter the following, replacing *IP address* with the address you want to block (for example, 69.63.176.13).
+
+```
+block drop from any to IP ADDRESS
+```
+
+To block a range of addresses, replace *any* with an IP address. For example:
+
+```
+block drop from 66.220.144.0 to 66.220.159.255
+```
+
+4. Enter the following to enable the packet filter and load the rule you created:
+
+```
+$ pfctl -e -f /etc/pf.conf
+```
+
+5. The IP address is blocked. To disable the rule, enter this command:
+
+```
+$ pfctl -d
+```
