Baker! An edit for the US DoD IP subnet!
US DoD owns the entire 11.0.0.0/8 subnet, not just 11.11.18.0/24 (limited scope)
Quick subnetting:
11.0.0.0/8 = 11.[0-255].[0-255].[0-255] different combinations.
Where as stated 11.11.18.0/24 (zero implied in IP) would indicate only 11.11.18.[0-255] different possibilities. But it cannot end in 255 as it is broadcast. Broadcast doesn't work traversing networks.
The importance in Q's question for Anons would possibly then be:
What's with the specific 11.11.18.0 mentioned?
Who's it assigned to within DoD, branch etc.?
Other things?
Not a USfag
