I installed WP on my home host machine which is dynamic ip address. The problem is that when ISP changed the dynamic ip address and then I try to use the new ip address to connect WP, the first main page is ok. But if I try to click the other pages from the main page, it points to the link that contains the old ip address. Of course it fails. For example, I onece used an IP address and it worked: http://184.108.40.206/blog/index.php. After a while, the ip address have changed to 220.127.116.11. The I try http://18.104.22.168/blog/index.php. This page can show no problem, but when I tried to click another page link, i.e.About. It still tries http://22.214.171.124/blog/about. That is wrong. How to fix this problem and why does it happen? Thanks!
