Can a host have 2 IP addresses?

Yes. All IP Routers (networking) are computers (hosts) with more than one IP Address. Even non-routers can have more than one IP address. Doesn’t even require additional physical NICs in the presence of virtual local area networks (VLAN).

Can multiple hosts have the same IP?

Yes. Two virtual servers on the same Application Switch or Web Switch can share the same virtual IP address as long as they are each configured with unique services or with different source networks.

Why would a server need multiple IP addresses?

Using different IP addresses segmented based on particular mail streams is another legitimate reason for using multiple IP addresses. Since each IP address maintains its own deliverability reputation, segmenting each mail stream by IP address keeps the reputation of each mail stream separate.

Can a node have multiple IP addresses?

NPM cannot combine multiple IP addresses for one node. If you only want to monitor the node using one IP address, you will have to add the other IP addresses to the discovery ignore list so they are not added by scheduled discovery jobs.

What happens if two hosts have same IP address?

If you mistakenly assign the same static address to two devices, you’ll run into a duplicate IP error. Eventually, your router will try to hand out that address to another device, creating an IP conflict. Another IP conflict scenario can occur if you have two DHCP servers on your network (which you should avoid).

How many IP addresses do I need?

So, very roughly, each user requires a little over two unique addresses. WhAT DO IP ADDRESSES LOOk LIkE? There are currently two different versions of IP addresses in use—IPv4 and IPv6.

Why does my MAC have two IP addresses?

The fundamental reason for this is that the MAC address is a hardware or burned-in address (data link layer) while IP addresses are from the network layer where more than one IP address can be assigned from your LAN segment to a single physical interface.

Can 2 computers have the same MAC address?

If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. Duplicate MAC Addresses separated by one or more routers is not a problem since the two devices won’t see each other and will use the router to communicate.
