Network

I find the 20 char which is from ?? s on last frame and i am sure that its right but either i am missing something or something is wrong with the challenge.

Convert hexadecimal to text

Hints:
1. In order to determine which machine is replying to which, consider VLAN ID and the transmitted Data
2. Consider carefully where to put the Source/Target MAC and Source/Target IPv6
3. The type of connection should be the same - 802.1Q Virtual LAN
4. The type of ICMP message should be Echo (ping) reply (0x8100) ///the Ping Request is type 0x8000///
5. Very helpful tool: https://www.gasmi.net/hpd/
