I am facing a really weird issue. As mentioned in the topic title, All the comments submitted originates from the same IP which is 18.104.22.168.
At first I thought it was spam from the same person. But guess what? I submitted a comment myself, and the IP is 22.214.171.124!
So just to confirmed, I ask my friend to submit a comment on my blog and his comment IP is also 126.96.36.199!
Please help me to debug this issue. I am using wordpress version 2.9.2
