The Beginning....Week 0
Lets answer why first! As we know IPv4 is 32 bits long address and it has an address range of 232 which is a total of 4,294,967,296 addresses. Due to expansion of network, setting up of huge data centers etc., IPv4 address will soon exhaust. Internet Assigned Numbers Authority (IANA) has given lot of thought on the current scenario and hence concept of migration to IPv6 has come into picture.
Well, where does NAT64 come in all this discussion going on? If you didn't realize most of our network is
So What exactly is NAT64? NAT64 is address translation mechanism that facilitates IPv6 network to communicate with IPv4 network and vice-versa. TAYGA implements NAT64.
TAYGA! Now what's this?
TAYGA is stateless implementation of NAT64. It is a daemon that performs translation of packets between IPv4 and IPv6. TAYGA is coded in C language .

What is our role in this ?
As we know, TAYGA is a stateless implementation. What we plan to do as a part of our project is to make it stateful.
Ahh! Now what is the difference between TAYGA stateless and TAYGA stateful?
In brief, currently TAYGA is implemented in such a way that it performs transparent mapping ,that is 1 to 1 mapping. For every IPv6 it assigns an IPv4 address. To make it Stateful, we are going to make N:1 mapping by maintaining the state via port number and IP address combination. Follow our blog to keep yourself posted.
