Question
In AWS, for VPC NACL (Network Access Control List) rules, Amazon recommends creating rule number by increments of 100. Why is this? (you can give an example to explain)
Answer
So you can add rules in between existing rules E.G rule 100 allows all inbound on port 80 but you want to backlist a specific IP (adding it after 100 will note help, so you add it as rule 99), but if you had rule 1 (with increments of 1) instead of 100, this would not work.
