These are obviously not all the same individual, though some of these are return visitors. Here are the easier identifications:

• 1 =2 =3 =4 =11 =12
  
• 5 = 29?
  
• 6 = 21 =22
  
• 7 = 15?
  
• 8 (= 20?)
  
• 9 = 13?
  
• 10 = 17? = 19?
  
• 14
  
• 16 ?= 23 = 26 29
  
• 18 = 20
  
• 24 = 30
  
• 25
  
• 28

A few of these, too, might also be the same individual using a different computer via a wireless network, etc.

But one way or another it is difficult to avoid the conclusion that up to a dozen different individuals visited one of the sites at ArcticCircle.ca using the same IP address.
