How can I tell if two IP addresses are on the same network?
When comparing two IP address/subnet combinations, the addresses must match for any section where the subnet value is 255. For a subnet of 255.255. 255.0, we expect to see the first three sections of the IP address match (reading left to right) if they are in the same subnet.
How are IP addresses assigned in a LAN?
There are two ways to assign IP addresses in a LAN. You can manually assign a static IP address to each computer in the LAN, or you can use a special type of server that automatically assigns a dynamic IP address to each computer as it logs into the network.
What happens if two hosts have the same IP address?
An IP conflict occurs when two or more hosts in the same subnet are configured with the same IP address. When this happens, communications with the two conflicting hosts are mixed up. One host may receive packets that belong to the other one, and vice versa.
Can you have two IP addresses?
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.
How do I connect to a different IP address on the same network?
How to change your public IP address
- Connect to a VPN to change your IP address.
- Use a proxy to change your IP address.
- Use Tor to change your IP address for free.
- Change IP addresses by unplugging your modem.
- Ask your ISP to change your IP address.
- Change networks to get a different IP address.
Does every router have a different IP address?
Your router itself has multiple IP addresses. It has a public IP address, a private “management” IP address, and then additional private IP addresses for each device in addition to the router’s internal IP, which is your LAN default gateway.
Can two devices 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.
How is an IP address related to a host address?
An IP address is always combined with a Subnet Mask, and it is the Subnet Mask that determines which part of the IP address that belongs to the IP network and which part that belongs to host addresses. The answer is within something called a Subnet Mask.
How to know if two IP addresses are in the same network?
The answer is within something called a Subnet Mask. An IP address is always combined with a Subnet Mask, and it is the Subnet Mask that determines which part of the IP address that belongs to the IP network and which part that belongs to host addresses. The answer is within something called a Subnet Mask.
How does host a and host B communicate?
Host to Host Communication. Since there are no Routers in this illustration, we know all the communication is happening within the same network — therefore, Host A and Host B are both configured with IP addresses that belong to the same network. Each host has a unique IP address and MAC address.
How are two hosts connected to one another?
Again, it is rare to find two hosts directly connected to each other. But understanding what it takes to get a packet from one Host to another Host is key to understanding how a Switch enables multi-host communication, or a Router enables multi-network communication. Both of these will be the subjects of the next articles in this series.
