Re: QIBM_QTG_DEVINIT

Hi Jay,

this is the IP address in "native" or "binary" - not in the usual "readable" 4-decimal-bytes-separated-by-dots form. 

Lets think of an IP address like:

   192.168.123.1

That would be 0xC0A87B01 in hex format. 

And that would be 3232267009 in decimal. 

That's how IP addresses are internally stored. The dotted notation is only for us humans. 

Subneting, routing, firewalls - all use these internal forms. 

Your address 173409066 would read as 0x0A56032A in hex or 10.86.3.42 in readable (dotted) form. 

HTH
Daniel
