IPv6 Dynamic DNS Now Available

We’ve released a minor update to our Dynamic DNS client to support IPv6. We’ve been working on this on and off for the last few months but didn’t really put any kind of rush on it because we didn’t believe that there was any demand for such a service.

Today though a question about IPv6 enabled dynamic DNS services came up on the ipv6-ops list, so we went ahead and finished it up for public consumption. It’s still business as usual for everyone using it for IPv4 dynamic DNS, but now there’s an IPv6 option. See the documentation for details. We have not added an AAAA record to acc.rollernet.us, so while there is auto-detect code for IPv6 clients in our Dynamic DNS client, there’s no way to take advantage of it just yet.

If anyone actually uses it for its IPv6 support we’d be interested in your feedback.

Global Crossing IPv6 Trouble

An issue with a customer’s IPv6 access was brought to our attention this morning. After some basic testing, it was apparent the traceroutes were stopping at our Global Crossing PE router (provider side) and we opened a trouble ticket with them to investigate.

A few hours later we discovered that the RIPE website was unreachable. Although the traceroute out indicated it was leaving our network via Sprint, we suspected the return traffic was trying to reach us via Global Crossing. After withdrawing our route announcements to GC we were able to reach RIPE and the customer who origionally brought the issue to our attention.

As this time we are waiting for a resolution on our trouble ticket with Global Crossing regarding this issue.

UPDATE [2011-03-06]: Global Crossing acknowledges that some recent MPLS changes in their network had caused our IPv6 to be null routed. They reverted the most recent changes and connectivity was restored. We will continue to monitor the situation.

Password Change Enhancements (Mail Box and Outbound)

We’ve made some enhancements to the password change pages for both Outbound accounts and hosted mail boxes. The account control center will now look for a matching outbound or mail box account by name and give you the option to apply the new password to both in one step.

The New Password Change Page

Also, we’ve added a random password generator button that will fill in a random 10 character password each time it’s clicked. There is no requirement to use the random passwords it generates and you can still edit it before applying the new password.

Banning AUTH Connections with Blank Login

We’ve started banning connections by IP address into our SMTP AUTH service that are making excessive connection requests with blank login names. This came about after we noticed multiple IP addresses flooding our server by attempting to connect once a second without ever attempting to send a login name. We consider this abusive as it wastes server resources that can be used to process legitimate connections.

Ehnancements to Mail Forwarding Management

We’ve made the following enhancements to the Mail Forwarding management section of the account control center:

  • A source search function has been added. Entering a search term will limit the displayed maps to those matching the search term.
  • Email address and mail box forwarding types are now displayed intermixed; previously they were grouped by type and sorted separately.
