Today I have requested a dedicated IP address for our websites from our hosting. Then I wanted to check whether the IP address got changed. I tried below statement.
And, it was showing the new ip address. But below statement is still showing the old ip address.
I tried with various other sites such as whatismyipaddress.com also. But everything is showing the old ip address only
So, I would like to know whether $_SERVER['SERVER_ADDR'] is the correct way of knowing the IP address of the server, or any other suitable way available?
I asked this question in LinkedIn and this below answer look appropriate.
In your case, indeed the correct method would be:
as this would echo the IP address of the server under which the current script is executing.
On the other hand;
will output the source of the homepage of a website. This IP address might differ from what you get from the previous method as this is what the out side world sees. Meaning if the website is co-hosted or virtualized then the latter will give you the edge IP address of the hosted infrastructure.
And, I found below function for finding actual IP address. I decided to find the IP address of the SERVER by requesting a page which displays IP address by calling below function. (The server will be the client for this request). But this approach also showing the new ip address. I am still wondering what will the code used in whatismyip.com for finding the actual IP of the host (device) instead of showing just the virualized ip.
