    Small business / private IP range: 192.168.x.x
    Large business / internal IP range: 10.0.x.x

    so where does 155.155.155.x come in? I have seen several companies using it now.

    just curious.

    thats pretty strange.. cos it isnt a private ip address range as far as i know..

    172.16.*-172.31.* is maybe what you're refering to (172.16/12)

    nope, definitely 155.155.155.x , subnet 255.255.255.0.

    I've been settin gup VPNs between my PC and clients, their external IP is grand (usually the 62.77 range) but some of the internal ranges on a few of the clients (three so far) are 155.155 etc.

    Nothing life threatening, just wondering why choose that IP range instead of the more usual ones...

    just someone changing 255 to 155

    RFC private ip's

    10.0.0.0
    172.16.0.0
    192.168.0.0

    169.254.0.0 auto-config IP according to M$
    the rest of the planet only uses it for DHCP hand shaking - ie. very unpredictable results if you use it.

    According to http://www.rfc-editor.org/rfc/rfc3330.txt ,
    " 169.254.0.0/16 - This is the "link local" block. It is allocated for communication between hosts on a single link. Hosts obtain these addresses by auto-configuration, such as when a DHCP server may not be found."

    Private-Use Network IP addresses (RFC1918) are (as you stated but with the subnet indicated):
    10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16

    These are recognised and used world-wide. With decent design and sub-netting, they provide plenty of addresses even for very big private networks.

    155.155.xxx.xxx is often used in lectures, papers etc. as an example of a Public address. Perhaps somebody has taken this literally instead of substituting an appropriate Private or Public addressing scheme?
