Why do results differ from my terminal?

Propagation. Authoritative changes can take up to the TTL of the old record to reach every resolver.

Can I look up private ranges?

No. RFC1918 and loopback addresses are rejected by the proxy to prevent SSRF.

Queries are resolved by PHP on the server (dns_get_record with a DNS over HTTPS fallback), which means you see what a public resolver sees rather than what your own ISP cached.
