This experiment pings a QUIC-able host. It can be used to measure QUIC availability independently from TLS.
This is the reference issue: https://github.com/ooni/probe/issues/1994
### A QUIC PING is:
- a QUIC Initial packet with a size of 1200 bytes (minimum datagram size defined in the [RFC 9000](https://www.rfc-editor.org/rfc/rfc9000.html#initial-size)),
- with a random payload (i.e. no TLS ClientHello),
- with the version string 0xbabababa which forces Version Negotiation at the server.
QUIC-able hosts respond to the QUIC PING with a Version Negotiation packet.
The input is a domain name or an IP address. The default port used by quicping is 443, as this is the port used by HTTP/3. The port can be modified with the `-O Port=` option.
The default number of repetitions is 10, it can be changed with `-O Repetitions=`.
### Usage:
```
./miniooni -i google.com quicping
./miniooni -i 142.250.181.206 quicping
./miniooni -i 142.250.181.206 -OPort=443 quicping
./miniooni -i 142.250.181.206 -ORepetitions=2 quicping
