Zeal online test series
When we use ipv6 and ipv4 together with the help of tunneling. So if the source set the hop count so will tunnel decrement the hop count. And if tunnel decrement it so wheater it decrement at both start and end of tunnel. Suppose source set hop limit to 16 and there are 2 router and tunnel on the path. So what will be the hop count after received by receiver.

Fragmentation Ipv4-Ipv6
True or false - 1. In Ipv4 fragmentation can be done both at Source and intermediate routers. 2. In Ipv6 fragmentation can be done only at Source and not intermediate routers. 3. In both IPv6/4 reassembly is done only at the destination. 4. ... fragmentation done at the Source in Ipv4? Should the 1) be false since segmentation is done and hence fragmentation can be avoided?
