It's not the host file it's the network settings in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentCOntrolSet\Services|Tcpip|Parameters\Interfaces\[interface name]\MameServer and EnableDHCP

That are modified. The change is reflected in the Network Properties GUI.

And with ipconfig but I'm with Ted... Who Cares?

This is much more efficient...

Code:
function geoip_country_name_by_addr($gi, $addr) {
if ($gi->databaseType == GEOIP_CITY_EDITION_REV1) {
$record = geoip_record_by_addr($gi,$addr);
return $record->country_name;
} else {
$country_id = geoip_country_id_by_addr($gi,$addr);
if ($country_id !== false) {
return $gi->GEOIP_COUNTRY_NAMES[$country_id];
}
}
return false;
}
function getdnsattributes ($l,$ip){
$r = new Net_DNS_Resolver();
$r->nameservers = array(“ws1.maxmind.com”);
$p = $r->search($l.”.” . $ip .”.s.maxmind.com”,”TXT”,”IN”);
$str = is_object($p->answer[0])?$p->answer[0]->string():’’;
ereg(“\”(.*)\””,$str,$regs);
$str = $regs[1];
return $str;
}
AND

Code:
$user_agent = $_SERVER[‘HTTP_USER_AGENT’]
function getbrowserver(& $MSIEversion, & $OPERAversion) {
$uag = $_SERVER[‘HTTP_USER_AGENT’];
if ( strstr( $uag, “Firefox” ) ) {
if ( preg_match( “#Firefox/(\\d+\\.?\\d*\\.?\\d*)#s”, $uag, $mt ) ) {
return “Firefox v{$mt[1]}”; }
return “Firefox”; }
........................
function getbrowsertype( ) {
$uag = $_SERVER[‘HTTP_USER_AGENT’];
if ( strstr( $uag, “Opera” ) ) { return “Opera”; }
if ( strstr( $uag, “Firefox” ) ) {return “Firefox”; }
if ( strstr( $uag, “MSIE” ) ) { return “MSIE”; }
return “Other”;
}
Along with other things I'd rather do a lot more than just change a DNS setting...
