===== Benefits of Using Aliases =====

# '''Simplification''': Instead of entering “192.168.5.3” into a firewall rule, if I make an alias, I can just enter “mailserver”, once I have set up a “mailserver” alias that directs to the mailserver.
# '''I can add to it!''' Let’s say I have 1 smart television in my house. I want to block it from going onto the internet to ''anything'' besides a single Netflix IP address, so I add a firewall rule to block it from going online to anything besides the Netflix IP address. Let’s say my family buys 3 more smart TVs… I don’t want to set up a new set of firewall rules each time. Aliases allow me to add '''''multiple IP addresses to a single alias!''''' Instead of having to make 5 new sets of rules, I can keep my existing firewall rules as they are, and simply add the new IP addresses to the alias.
# '''Maintainability''': When you need to update multiple firewall rules, you can just update the alias instead of each individual rule.
# '''Readability''': Aliases make firewall rules more understandable by using descriptive names instead of raw IP addresses or port numbers.
