HI This would be really useful, I also need this functionality

I hacked this in to support only the scenario that I needed, ipv4 and ipv6 lookups.

Multiple values are separated by commas:

sudo -E python3 ./dnschef.py --interface 0.0.0.0 --fakeip '127.0.0.1,192.168.200.201' --fakeipv6 '2001:db8:3333:4444:5555:6666:7777:8888,2001:db8:3333:4444:5555:6666:7777:5555'
