What happens if two computers have the same IP address?
Two computers can safely have the same IP address in certain cases.
In most cases, if those two computers are on the same local network, it breaks connectivity for one or both of them.
Internet protocols work by sending small, individually addressed messages..
Can I have 2 DNS A records?
You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy and fallbacks. Additionally, multiple names could point to the same address, in which case each would have its own A record pointing to that same IP address. The DNS A record is specified by RFC 1035.
Why are there 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 DNS name have multiple IP addresses?
To answer your question in short, yes it can happen. DNS, the Domain Name Service, as you would know, is used to help us resolve Fully Qualified Domain Names (FQDN) to IP addresses. … This is what gives a DNS name multiple IP addresses.
Can you run multiple websites off a single IP address how?
IP-based virtual hosting is a method to serve different websites based on IP address. You can assign a separate IP address for each website on a single server. In this section, we will use the IP addresses 192.168. 0.101 and 192.168.
What happens if two devices have the same IP address?
Conflicts arise when two devices are on the same network trying to use the same IP address. When this occurs, both computers end up not being able to connect to network resources or perform other network operations.
What happens with duplicate IP addresses?
For IPv4, IP-packets sent to the duplicate address will be sent to the MAC address currently in the ARP cache. Flapping will only occur if both hosts send ARP replies to the sender, flapping the ARP entry. If no ARP replies are received, connectivity will be fine with one of the owners of the duplicate IP.
Why do some websites have multiple IP addresses?
A Website can have multiple IP addresses when you hosted it at multiple locations. Why? It can be for load balancing or redundancy.. Or to serve web pages based on the user location etc.. If you are using Linux, you can use tools like dig to get DNS information for a specific website.
Can one IP address have multiple hostnames?
Yes, this is an extremely common practice. It is called a Shared Web Hosting: In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple hostnames on a single machine with a single IP address.
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 two hosts have same IP?
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 more than one IP address?
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).
