Assalam-o-Alaikum,

This article is about getting Dynamic IP's for domains such as youtube.com and facebook.com. This is useful when particular task is needed to be done for such domain, tasks such as different route, QoS, prioritization, etc.

Lets Start...

First I will cover the CLI section, then I will show snapshots of the same.

The following example will be done for youtube.com and facebook.com


Section 1 : CLI

1.1 Create firewall rules to add each IP visited by users to a dynamic IP Address-List which can be used later.

/ ip firewall filer add chain=forward action=add-dst-to-address-list protocol=tcp src-address=10.10.0.0/16 address-list=my-youtube address-list-timeout=0s content=youtube.com comment="youtube.com IPs"

/ ip firewall filter add chain=forward action=add-dst-to-address-list protocol=tcp src-address=10.10.0.0/16 address-list=my-facebook address-list-timeout=0s content=facebook.com comment="facebook.com IPs"

/ ip firewall filter add chain=forward action=add-dst-to-address-list src-address=10.10.0.0/16 address-list=my-facebook address-list-timeout=0s content=fbcdn.net comment="Facebooks content delivery network IPs"
