[AusNOG] another ipv6 Q

[Mitchell Warden]

The RFC prohibits this. If you already have a /24, I don't think it will cost you any more in APNIC fees to add a /48.



   6to4 prefixes more specific than 2002::/16 must not be propagated in     native IPv6 routing, to prevent pollution of the IPv6 routing table     by elements of the IPv4 routing table.  Therefore, a 6to4 site which     also has a native IPv6 connection MUST NOT advertise its 2002::/48     routing prefix on that connection, and all native IPv6 network     operators MUST filter out and discard any 2002:: routing prefix     advertisements longer than /16.Cheers.

Why, I didn’t say I wanted to use the ipv6 to ipv4 mechanism, I just want to use a /48 ipv6 range that nobody else can lay claim to.. well for as long as I   have the ipv4 /24   

   

This was more of a thought problem than anything else.

This is a strange question.  
  

     
  

One thing that some engineers don't seem to understand is that IPv4 and IPv6 have absolutely nothing to do with each other.  At no point do they communicate with each other unless some translation method is used... but that method is doing   the interpretation.    
  

     
  

Even dual-stacking v4 and v6 on the same interface doesn't make them interact in any way whatsoever.

Hi
  
  So we have a ipv4 class C assigned to us. What if any pitfalls are there for using the ipv4 in ipv6 address space ?
