config: Add IPv4 Address config debug logging
Per ticket #32888 this should address logging "the Address torrc option", "and whether it is an IP address, or a DNS name"; or the detected "local hostname", "and whether it is an IP address, or a DNS name". Some of these details already seem to be logged, so just add what's missing. --- src/app/config/resolve_addr.c | 6 ++++++ 1 file changed, 6 insertions(+)
