What are non routable networks?

 

Hi there,

Non routable networks are basically the IP addresses that are used inside a firewall. These IP address are used on the internet so therefore conflicting issues will arise if users are connected to a site somewhere else.

Will there be any risk to a system having them?

• These address are the internal ip range of a firewall and secure access to these from outside from outside requires passing them through the firewall which is standard practice in general.

Typically Ip address reserved inside the firewall are ranged:

10.0.0.0 – 10.255.255.255

 172.16.0.0 – 172.31.255.255

 192.168.0.0 – 192.168.255.255.

Hope that explains it.
