I found somewhere on the internet that routers also have a MAC address. Is it true? If so, how can I make it undetectable?

Everything that uses Ethernet has a MAC-address, there's no real way to block it out, and besides, why would you? If you block that out, for some reason, it will effectively stop all ARP Communication, which in turn would lead to you not being able to communicate with anything that's connected to and from that router, including your LAN AND the internet.

You can, however, in some cases change the MAC address, and by doing so, mitigating links between your MAC and IP address (provided that you change IP-address as well), but to completely "block" or "erase" the MAC would render your router useless, apart from being a plastic box with some flashing lights on it.

Yes, all devices on your local network will have a MAC address.

MAC addresses are low level addresses, used for local network switching, and are not broadcast to any websites. You do not need to worry about blocking it.

Websites using third party tools or plugins (such as Java) may be able to retrieve it, but simply visiting a website will have no access to this.
