Are IPv6 auto-configured addresses transient?

2009-10-07 Thread Vijayrajan ranganathan
Hi Everyone, Is there a notion that auto-configured IPv6 addresses based on globally unique prefixes are transient compared to manually configured ones? I know that we could configure them to have infinite lifetimes & such, but I am thinking of a large IPv6 deployment where these addresses are expe

Hi, Perhaps a naive question, but can somebody mention some practical use cases for advertising multiple prefixes in a Router Advertisement? Thanks & Regards Vijay IETF IPv6 working group mailing list ipv6@ietf.org Administrative

Hi, If I want to use more than 1 loopback IPv4 address, I can assign one from 127.0.0.0/8 address range. Does IANA reserve some IPv6 address range for loopback communication? If not, what is the best address range to use for assigning such an IPv6 address? Thanks & Regards Vijay -

do these come from? What happens if they need to host a large number of virtual OSes, do they pre-allocate these, any ideas? Thanks & Regards Vijay On Thu, Jul 2, 2009 at 4:45 PM, Aleksi Suhonen wrote: > Vijayrajan ranganathan wrote: >> >> I did consider using vlans but

Hi Thomas, I have an interface that is shared by multiple virtual hosts on the box, each of which requires autoconf addresses. The one standard address can't be shared as, in my implementation, the IP address is the one that uniquely identifies the virtual host for an incoming connection. These ad

Hi Everyone, I have an ethernet interface for which I am defining the Interface-ID in a different manner. For an ethernet interface with MAC "34-56-78-9A-BC-DE", I am defining the Interface-ID to be "34-56-78-xy-zw-9A-BC-DE" instead of "36-56-78-FF-FE-9A-BC-DE" where x,y,z,w are my implementatio
