Hello, If you don't make use of BitFolk's secondary DNS service then you can ignore this email as it has no impact on you. c.authns.bitfolk.com has been renumbered: 209.20.91.73 → 173.255.227.192 2001:4978:f:392::2 → 2600:3c03::31:2053 This actually has nothing to do with BitFolk's renumbering. c.authns used to be hosted at Slicehost which recently got bought by Rackspace, and they are also renumbering. Most people don't need to do anything. The glue record for c.authns.bitfolk.com has been updated so over the next couple of days the new IP will start being used. If you have made your own DNS records that pointed at 209.20.91.73 or 2001:4978:f:392::2 (for example if you made nameserver host names inside your own domain(s)) then you will need to update them. It is recommended not to use such names because of the need to change them in so many places. You may also have ACLs that allow zone transfer from 209.20.91.73. These normally don't get used since the BitFolk nameservers try to do zone transfer from each other first. If you do have such an ACL then you will need to update it. 209.20.91.73 and 2001:4978:f:392::2 will go away on 19th March.
