local-etc-hosts-updater

Queries the mDNS record for a given .local address, and maps it to the given subdomains inside a hosts file

Linux >5.1 only due to SO_BINDTOIFINDEX socket option.

Usage

local-etc-hosts-updater <local_domain> <ip_version> <scope_id>

local_domain is the local domain to be queried
ip_version is an enum.
- 4 will query for an IPv4 address in the 192.168.0.0/16 subnet
- 6 will query for a ULA IPv6 address in the fd00::/8 subnet
- 0 will do both
scope_id is either the name of the interface, or the corresponding numeric interface index. The index is largely for unrooted android limitations.
