Usage

Default dual-stack detection:

bash <(curl -Ls Net.Check.Place)

IPv4-only test:

bash <(curl -Ls Net.Check.Place) -4

IPv6-only test:

bash <(curl -Ls Net.Check.Place) -6

Latency mode:

bash <(curl -Ls Net.Check.Place) -P

Low data mode:

bash <(curl -Ls Net.Check.Place) -L

Skip specific sections:

bash <(curl -Ls Net.Check.Place) -S 1234567

Bilingual support:

bash <(curl -Ls Net.Check.Place) -l cn|en

JSON output (Example Output):

bash <(curl -Ls Net.Check.Place) -j

Skip checking OS and dependencies:

bash <(curl -Ls Net.Check.Place) -n

Auto-install dependencies:

bash <(curl -Ls Net.Check.Place) -y

Display full IP addresses in the report:

bash <(curl -Ls Net.Check.Place) -f
