Hello serverfault Universe,

My ever evolving and expanding local area network is currently using a class-C address. My network consists of multiple subnets depending on site/location.

192.168.1.x is site HQ 192.168.5.x is secondary site 192.168.10.x is so on and so forth.

Long story short - I have inherited this network design from the previous admin who has left the company which started off with a dozen people and now has just over 300 full time/part time employees. We do not yet have client VPN access; but we do have site to site VPN setup.

My question is, in preparation for outside client access to my network via Cisco ASA, I would like to re-address the HQ site because I understand a 192.168.1.x or 192.168.0.x are not very good choices for a company subnet - it may conflict with a home user's LAN when connecting to my LAN, I believe? Through your experience, does anyone out there have any suggestions and tips on how I can proceed with re-addressing my subnets. If I designed this network I would have gone with a 10.0.0.0 (mask 255.255.255.0) so I am leaning towards changing it to fit. Thank you.
