IP Redirect Issue in WP 3.1, 3.1.1, 3.1.2

I’m currently running WordPress 3.0.3 and with versions 3.1, 3.1.1 and 3.1.2 (current version), it kicks me out and makes me re-login every time I click on one of the page buttons or if I search within posts, comments and a few other places:

I’ve just noticed that on version 3.0.3, if I hover over the Page 2 link in the Posts page to get to the second page of posts, this is the link it sends me to and it works just fine: (https://www.in.gov/visitindiana/outdoorsblog/blog/wp-admin/edit.php?paged=2 )

On version 3.1, 3.1.1 and 3.1.2, here is the link it sends me to (and it then kicks me out to re-login:
(https://192.1.1.1/visitindiana/outdoorsblog/blog/wp-admin/edit.php?paged=2)

I’m wondering if the 3.1 and beyond versions could be keying off the host or server ip parameters in the HTTP header. Since this comes through via the IN.gov proxy servers, they see my server as 192.1.1.1.

Did WordPress change it to pull the host name instead of a static entry in 3.1 and higher versions? If so, is there any way for me to fix this? The site itself runs just fine for consumers, but on my back end, I have to re-login every time I page through posts, pages, comments, users (or do a search within wp-admin for any of those things either).

Can anyone help?
