I agree that the php_gethostbyname call should NOT return the hostname if it fails. My problem is that it is failing for no good reason, as it seems others have reported. My server is a production 4.1 BSDI system with perfectly functioning resolver libraries. vp3: {225} % dig vp3.netgate.net ; <<>> DiG 8.2 <<>> vp3.netgate.net ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUERY SECTION: ;; vp3.netgate.net, type = A, class = IN ;; ANSWER SECTION: vp3.netgate.net. 12H IN A 205.214.170.247 Yet, this fails: $sitename = "vp3.netgate.net"; $ipadres = gethostbynamel($sitename); $count = count($ipadres); echo "$count"; for ($i=0; $i<$count; $i++) { echo(" $ipadres[$i] "); } With this output: Text generated by PHP 0Open Connection Failed 0 I'm in complete agreement with you that gethostbyname should not return the hostname, gethostbynamel seems to work correctly. But, why is it failing? If I fall back to a 3.0.14 things work perfectly. Let me know what I can do to help track this down.
