ISP best practice

[Roel Reyes]

Hi all, 

Is it better to manage my Core routers gateway with public ip? or can i make it private ip? i tried using private ip and base on traceroute my private ip is exposed, does it matter with direct internet or dedicated internet clients seeing a private ip in traceroute?

or if you can provide me  any guide or articles for a Startup internet service provider like providing hotspot and serving OTT? other that cisco press. 

Thanks all.

Hi

A public IP is configured on the interface facing to the Internet provider and most of the time the device is a firewall or a router with firewall IOS. I suggest manage the devices with a internal IP address (private), it is by security purposes.

I think i have read, some guides that ISP core routers should use routable internet address.
