What does IPv4 mean?
IPv4 is an Internet Protocol version that uses 32-bit addresses. Home networks commonly use private IPv4 addresses internally and translation toward internet access. An IPv4 address identifies network addressing, not a streaming account or a particular video quality.
Why it matters
Clients may obtain their configuration automatically through DHCP. Entering another household's address, gateway or mask can break connectivity. A public server address and a private player address have different roles. Do not publish account-bearing URLs just to demonstrate an IP detail. On a dual-stack connection, IPv4 and IPv6 can provide different paths, so a fault on one needs a controlled comparison rather than a universal protocol judgement.
