I'm using ubuntu and can use python if needed to try and find the ipv6 address of another computer. I already know the other computer's ipv4 address.
Previously, I had to find the mac address of this other computer and I used
arp -an <ip_addr> and parsed for the mac address to return it. Is there anything similar that I can do via linux or python to search/ping by ipv4 and return more information of that host like its ipv6 address?
