From SA-MP Wiki

Description:

Get the specified player's IP address and store it in a string.

Parameters:

(playerid, ip[], len)

playerid

The ID of the player to get the IP address of.

ip[]	The string to store the player's IP address in, passed by reference.

len	The maximum length of the IP address (recommended 16).

Return Values:

The length of the player's IP address. -1 if player specified doesn't exist.

The player's IP address is stored in the specified array.

Notes

PAWN is case-sensitive. GetPlayerIP will not work.
This function does not work when used in OnPlayerDisconnect because the player is already disconnected. It will return an invalid IP (255.255.255.255). Save players' IPs under OnPlayerConnect if they need to be used under OnPlayerDisconnect.

public OnPlayerConnect(playerid)
{
    new plrIP[16];
    GetPlayerIp(playerid, plrIP, sizeof(plrIP));
    if(!strcmp(plrIP, "127.0.0.1"))
    SendClientMessage(playerid, 0xFFFFFFFF, "Welcome to your server, master :)");
    return 1;
}
