Considering this, can a host have two IP addresses?
A single physical network card definitely can have multiple IP addresses. This is almost essential when implementing server virtualization: with multiple virtual servers running on the same physical hardware, each needs its own IP address. Yes you can have more than one IP address when using a single Network Card.
Additionally, can you have more than 1 IP address? Although it is not at all recommended to assign multiple IP addresses on a computer until there are multiple network interface cards or NICs installed in it, you can still do so. The reason why it is not recommended to have multiple IP addresses on a single network adapter is to avoid the bottlenecks.
Besides, how many IP addresses can a host have?
The 255 address (in binary notation, a host address of all ones) is used to broadcast a message to every host on a network. Just remember that the first and last address in any network or subnet cannot be assigned to any individual host. You should now be able to give IP addresses to 254 hosts.
Can one network card have two IP address?
Yes you can have more than one IP address when using a single Network Card. Setting this up is different in each Operating System, but may involve creating a new Network Interface. This can look like a unique connection but will be using the same Network Card behind the scenes.
