why both no_ipv6/no_ipv4 and also resolve_strategy in escaper configs

[GlenDC]

Asking as it seems to result in essentially the same thing:

no_ipv6: true
resolve_strategy: IPv4Only

Seems like if you have one you don't need the other? As in, resolve_strategy alone seems to be fine on itself. In fact if I check the code it seems to set the no_* properties based on this anyhow, if none are set. So why are both of these approaches possible / supported? Is there a (subtle) difference I am missing?

resolve_strategy will only take effect when resolving domain names. You can set it to ipv4_first if you have both v4 and v6 address. And you can set it alone to ipv4_only but still allow v6 access if the client request an ipv6 target address directly.

Understand, and no_ipv6 is just about the escaper on whether or not it can establish an no_ipv6. Can also see that in escaper src code like g3proxy/src/escape/direct_float/tcp_connect/mod.rs and others.

Thanks for clarifying. Clear to me now. Going to close this issue as resolved. If you think this can result in maybe a desire to improve the docs, do let me know, I'll gladly contribute that to thank you for your patience and time. Take care.

Yes it's welcome to help us to improve the docs. I'm not good at that indeed.
