Is the US Department of Defense ip address 6.3.6.0 valid? (reported by Apple products)

  • 772

I've recently seen a lot of this IP address. A geo ip lookup tells me it is US Department of Defense Network in Arizona so why do some routers (here and here) default to this address?

The real question is should I treat 6.3.6.0 as an incorrectly reported ip address or not?

I have only anecdotal evidence of this so I wondering if am i missing some inside joke... or maybe the US Department of Defense produces routers and is particularly active :)

    It's a legitimate address range - if Apple's using it as a default address for their routers, then they're doing it wrong.

    ARIN confirms that the whole 6.0.0.0/8 range is assigned to "USAISC", and if you take a look at a BGP looking glass, you'll see that 6.3.0.0/18 is being actively routed on the internet by AS668, which is assigned to the US DoD.
