go-mockdns's Issues
No tagged version
Hi,
It would be nice to have a tagged version of go-mockdns, to be able to more cleanly import it in go.mod files and to make sure the API/interaction does't change in the future.
apart from that, great module, thanks 👍🏻

[Feature Request] Options of server listen addresses
Thanks for the awesome library!
It's usage could be more extensive if there are options for mockdns.NewServer to specify server listen addresses (TCP/UDP).
