Can I use this with IPv4 addresses?

No, the %interface syntax is specific to IPv6 link-local addresses and is not used with IPv4 addresses.

Explanation:

• IPv4 Addresses: In IPv4, addresses are typically global or private and do not have the same scope limitations as link-local addresses in IPv6. Therefore, there is no need to specify an interface when pinging an IPv4 address.

• Ping Command: When you use the ping command with an IPv4 address, you simply provide the address without any interface specification. For example:

  ping 192.168.1.1

Summary:

While you can use the ping command with both IPv4 and IPv6 addresses, the interface specification (like %eth1) is only relevant for IPv6 link-local addresses. For IPv4, just provide the address directly.
