Hello Gerrit,

Today it wouid seem that way. But in the haydays of Fidonet syssop were always eager to try out new technology and even spend considerable amount of mobney on it. ISDN was embraced and so wsa DSL. Now FOIP is the rule rather than te exception. So why the reluctance to embrace IPv6? Contrary to ISDN, it doenn't have to cost anything in most cases. Complexity? Oh c'mon, ISDN was far more complex to install than IPv6.

Than these admins have not understood or they are just lazy. Yes, a dusl stack system is moe complex than a single stack IPv4 system. But IPv6 by itself is not more complex than IPv4. On the contrary I would say. IPv6 is less complex. But it is different, there is a learning cuve and one has to "unlearn" some of the "IPv4 think". But once past that, it is relatively easy. And unavoidable in the long run anyway...


Cheers, Michiel
