Whither IPv6? An IPv6 Primer & Recommendations

Whither IPv6? Introduction IPv6 (Internet Protocol, version 6) is a replacement protocol for IPv4, which we have today. IPv6 was primarily developed to stave off the impending exhaustion of the IPv4 address pool.

Our recursive service has this really cool feature that allows whomever is providing the service to its users (your Internet Service Provider) to select what sites it thinks you should be warned about. They can configure it to block the site completely, or provide a warning before you get…

Propagation Time

What’s the biggest complaint about DNS? Propagation time — specifically, the time it takes for DNS changes to become widespread across the Internet. Any DNS provider using anycast with nodes in multiple locations should be able to implement changes pretty quickly, but the Internet is a pretty big enigma. Have you thought about the size […]
