Hello Tommi,

The second IBN is not to protet against failure of the DNS service wheren vlist.eu is registered. Eurodns.com is very reliable, it has never failed me in all those years. fido4to6.vlist.eu is a cname for de8.portmap64.net. It is a leftover from my Ds-Lite emulation experiments. It points to the IPv4 adres of the 4 to 6 port mapper of Feste-Ip.net.

Now it works as failover for those who do not have IPv6 to connect to my sytem if my incoming IPv4 fails on this end.

 TK> Why not just add multiple A's and AAAA's under one name?

To indicate that fido4to6 is not the prefered choice. It is my understanding that most systems will never try the second IBN first.


Cheers, Michiel
