The Net may have briefly routed around Turkish prime minister Recep Tayyip Erdoan's DNS-based anti-Twitter censorship
, but the minister's next move has been to mandate that Turkish ISPs block Twitter's assigned IP addresses
. Reports Ars Technica: " This move essentially erases Twitter from the Internet within Turkey—at least to those people who don’t have access to SMS messaging, a foreign virtual private network or Web proxy service, or the Tor anonymizing network.
'We can confirm that Turkey is now blocking the IP addresses of Twitter after the previous DNS blocking technique proved ineffective,' said Doug Madory, of the Internet monitoring company Renesys, in an e-mail to Ars. A Turkish government webpage shows that there is an IP address block order in effect for 18.104.22.168, the primary IP address for twitter.com."
