Title: DNS weirdness from wordpress.org?

Hangs for quite some time on trying to resolve wordpress.org. Still kinda coming back to a DNS issue in my mind. Although if I dig or nslookup wordpress.org, it resolves very quickly lol. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057062) * Could it be a local DNS issue at your ISP’s end? * Thread Starter [incursio](https://wordpress.org/support/users/incursio/) * (@incursio) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057064) * Possibly, but if I ping, dig, or nslookup, it resolves super fast. wget hangs a while, and it uses curl, I believe … * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057079) * Other than a purely local issue, I have no idea why this is happening only on your site. * Thread Starter [incursio](https://wordpress.org/support/users/incursio/) * (@incursio) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057082) * Yeah, it’s definitely something local to the environment, or possibly upstream at my provider (it’s a dedicated server in a colo). Making me crazy though lol, as I’ve had to temporarily disable comments due to the flood of spam that Akismet isn’t able to pick up now. * Akismet status shows all servers green, but I get the dreaded “can’t connect to Akismet” message. Which is probably due to a timeout in cURL, I would imagine. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057087) * If it’s local DNS, it should resolve all by itself in a few hours – assuming the DNS servers update correctly this time, yes? * Thread Starter [incursio](https://wordpress.org/support/users/incursio/) * (@incursio) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057089) * Okay, I think I’ve found something here. If I use the -4 command line switch to cURL, it works lightning fast. So this means it is trying to resolve it first as an IPv6 address, then falls back. And in looking at my phpinfo() output, it seems that the cURL extension is configured to look for IPv6 as well. Need to figure out how to do that without having to build the cURL extension manually( since I use yum). * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057096) * I know we’re all down to the last few thousand IPv4 blocks but has someone been jumping the gun making IPv6 the default for cURL? I couldn’t claim to be anything near an expert but surely it make sense to keep IPv4 the default with a fallback to IPv6 for the next couple of years at least? Weird… * If I spot one of the more server-orientated forum regulars around, I’ll try to flag them down and point them in this direction. * Thread Starter [incursio](https://wordpress.org/support/users/incursio/) * (@incursio) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057102) * I’m running PHP v5.3.3, so I’m pretty sure I could go in and edit class-http. php and functions.php, and anything else that calls curl_setopt() and add in the CURL_IPRESOLVE_V4 option, but I’d rather not hack core lol. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057106) * I’m running PHP 5.3.3 myself but I’m not having the same problems. * Thread Starter [incursio](https://wordpress.org/support/users/incursio/) * (@incursio) * [13 years, 7 months ago](https://wordpress.org/support/topic/dns-weirdness-from-wordpressorg/#post-3057115) * I installed Dion Hulse’s most excellent core control plugin, and disabled cURL as a valid transport, and things are good. But still … lol.
