Hi all, i have Googled this but could do with asking a few questions about it. I would be grateful if someone could answer the following for me. 1. i understand that an IPv4 uses a 32 bit address and how the sub net mask works,as the IPv6 uses a 128 bit address can both types be used on the same network?. 2. does the IPv6 version use the same type of network class identification as the IPv4, if so how?. thans in advance Gary

Yes - as long as there is IPv6 support on the network.

What do you mean by 'class'? If you mean the old classful types - A B and C etc then no. Such things only barely exist on IPv4 networks these days.

Thanks Harry, so i take it that Ipv6 provides such an abundance of addresses that its not necessary to separate networks into different classes.( Class A B etc) Gary

 

Correct. And IPv4 isn't so divided any longer either. It was very wasteful of addresses!
