-/* 0701: disable IPv6
- * IPv6 can be abused, especially with MAC addresses, and can leak with VPNs: assuming
- * your ISP and/or router and/or website is IPv6 capable. Most sites will fall back to IPv4
- * [SETUP-WEB] PR_CONNECT_RESET_ERROR: this pref *might* be the cause
- * [STATS] Firefox telemetry (Sept 2022) shows ~8% of successful connections are IPv6
- * [NOTE] This is an application level fallback. Disabling IPv6 is best done at an
- * OS/network level, and/or configured properly in VPN setups. If you are not masking your IP,
- * then this won't make much difference. If you are masking your IP, then it can only help.
- * [NOTE] PHP defaults to IPv6 with "localhost". Use "php -S 127.0.0.1:PORT"

 /* 0702: set the proxy server to do any DNS lookups when using SOCKS
  * e.g. in Tor, this stops your local DNS server from knowing your Tor destination
  * as a remote Tor node will handle the DNS request
