Nisha on Tamil music (78 = 73 = 79 = 72 = 75)

We have been tracking a group of Rogers' IPs to see how they could shift in the years 2003-5.  One of the most useful sources of data have been message boards that post both a handle and an IP for each post.  Combining name, IP, and time has shown several interesting shifts.

Another case in point are the posts of a certain "Nisha" on a board concerning Tamil music (here).   Googling "Nisha" on this site gives 80 or 90 posts on a variety of subjects from July 2002 until December 2004. Almost all of these posts report her IP as 66.185.84.78 -- a Rogers IP that is part of the pool that we've been tracking.  At several points, however, Rogers seems to have shunted her off to another IP. The first is in the summer of 2003:
    Jul 18 2003 18:46:51 66.185.84.78
    Jul 31 2003 21:29:40 66.185.84.73
    Aug 5 2003 00:32:37 66.185.84.78
Something similar happened in February '04:
    Feb 5 2004 21:25:49 66.185.84.78
    Feb 6 2004 20:26:01 66.185.84.78
    Feb 6 2004 20:32:23 66.185.84.79
    Feb 11 2004 19:15:47 66.185.84.78
Nisha seems to have left the board for a few months beginning in Sept. '04, but returned with these edits:
    Nov 11 2004 17:01:35 66.185.84.68
    Nov 12 2004 18:33:37 66.185.84.68
    Dec 1 2004 15:23:25 66.185.84.72
    Dec 22 2004 12:31:48 66.185.84.75
In all three cases, the general picture is as we have seen previously.  Although almost all of her posting comes from x.x.x.78, Rogers can shift her to other numbers in the pool as needed.
