bug: `/etc/hosts` is not respected about trippy

[notramo]

I didn't have time to test it yet as it's not shipped on Void Linux, and I would have to compile the latest release from source because there is no musl binary release provided.

@fujiapple852, I have tried the latest version, and it worked.

Thank you for the bug report @notramo. Can you confirm:

• The OS you are running on
• The trippy version
• The trippy command line arguments, in particular whether you are using the -r or --dns-resolve-method flags
• If the issue is with resolving hostnames to IPs or reverse lookup of hostnames from IPs

By default, trippy uses the libc provided getaddrinfo and getnameinfo functions (indirectly via the dns-lookup crate).

[fujiapple852]

Confirmed that trippy respects entries from /etc/hosts for both DNS lookups and reverse DNS lookups when using the system resolver (tested on Linux).

@notramo can you confirm on the details above?

Thanks @notramo, we can leave this open for now.

Note that musl builds have been re-enabled for 0.8.0 (they were disabled for 0.7.0 due to #456)

I’m not familiar with Void Linux, is there a package manager / repository that trippy could be added to so that it can be installed on that platform?

Added a help wanted packaging request for Void Linux: #547

@notramo 0.8.0 has been released and includes a musl build: https://github.com/fujiapple852/trippy/releases/tag/0.8.0
