There is no ipv6 addr when i specify hostname #81

Closed shashenli closed 6 months ago

shashenli commented 9 months ago

when i use command like ./mdns_example --service _airdrop._tcp.local. --port 8770 it works fine but when i use ./mdns_example --service _airdrop._tcp.local. --port 8770 --hostname sddwswdd it will never answer AAAA record
