how do i do a php redirect for muiple ip values where only the first octect (i.e. 192.168.1.98 fist octect is 192) 5 then the rest change

if(substr($_SERVER["REMOTE_ADDR"],0,3) == 192){
// do redirect here
}

 

That should do the job

if(substr($_SERVER["REMOTE_ADDR"],0,3) == 192){
// do redirect here
}

 

That should do the job

 

Just remember, This method will work but for a local network only.

I wasn't aware of that as far as I was concerned it would work externally as well.

 

It doesnt matter in this case as 192.168 is a reserved local network but just out of interest why wouldn't it work externally?

I'm sad enough to have studied CCNA twice

 

I might have misinterpreted what Shaun was trying to say. What I was asking is why $_SERVER["REMOTE_ADDR"] would only work with local IP addresses?

 

Wouldn't the following code which uses the start of a public IP work in the same way?

 

if(substr($_SERVER["REMOTE_ADDR"],0,3) == 216){
       // do redirect here
}

Because the IP your useing is internal, If you was to upload this script to a server outside of your internal network the script could not see that your IP is 192.168.1.2, It would see an external IP such as 88.2.45.120 or something simler. (www.whatismyip.com)

Ah I see what your saying thanks for the clarification a bit of a slow moment me thinks!

 

I thought you were saying that $_SERVER["REMOTE_ADDR"] just wouldnt work with external IP's

No it definatly works for external

// OT

 

Holy crap. You've actually managed to cover CCNA 2 times and not know what internal and external ips addresses are - you seriously have to be kidding me? IIRC, in session 1 or 2 they go all over IP addresses, reserved addresses, DNS etc. in some detail.

 

I know full well what the difference between between internal and external IP's are thanks... I'm an assistant network manager so I think it may be a necessity for me to understand them dont you!

 

That really wasnt what I was asking if you actually look at what I said in my previous post it was simply a misunderstanding as to what Shaun was getting at.

Perhaps stop bitching at each other?
