DNS Matters

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. IPv4 is a 32 bit binary number, represented in decimal form, such as 204.74.108.1 (which happens to correspond to pdns1.ultradns.net). This 32-bit IPv4 address pool provides approximately 4.2 billion unique addresses that may be used by systems on the Internet. In contrast, IPv6 ad...READ MORE

My current non-work project is helping my elderly mother write her life stories. She uses Google docs, which makes it easy for me to rollback changes when she accidentally deletes a story. When she gets stuck working her laptop (which is often), I use a remote desktop application to help her. She is having a great time reconnecting with friends and discovering how much great information is out there. However...She does not read error and dialog boxes, because nothing contained in them makes s...READ MORE

Amid quite a lot of hoopla the root DNS zone of the global public Internet "graduated" into full DNSSEC operation on July 15 (give or take a day depending on the timezone). Having been involved with DNSSEC since it was still a DARPA research project in the mid 1990's, I don't know whether I want to be happy to see this (joining in the crowd of folks congratulating each other on a job well done) or just a little cynical that it took so long to get here (joining in with the crowd that...READ MORE

We’ve recently gotten some coverage regarding our recursive service blocking parked domains. (Recursive is the part of the DNS puzzle that answers end-user requests to the Internet.) We aren’t doing that! 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...READ MORE

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 of the DNS database, and how changes get out to the rest of the Internet? Neustar thinks about it all the time.On the first point, Neustar UltraDNS isn’t just...READ MORE
