To answer your question briefly, yes, it can happen. As you know, DNS, the Domain Name Service, is used to help us resolve Fully Qualified Domain Names (FQDN) to IP addresses. … Because of this, a fault-tolerant DNS service is implemented that splits DNS queries between multiple different DNS servers.
Can a hostname have multiple IP addresses?
The hosts file does not differentiate between different types of records when it is resolved. So for hostname to IP address mapping, you only get one IP address per hostname (but multiple hostnames can resolve to the same IP address, which is the opposite).
Why are multiple IP addresses associated with the same domain name?
Why are multiple IP addresses mapped to the same domain name (e.g. and )? Each network’s configuration assigns different DNS servers to lookup IP addresses, which can result in different IP addresses for a site. The main reason for this is to reduce network congestion10.
Can a device have 2 IP addresses?
Yes, you can have multiple IP addresses using a single NIC. This configuration is different in each operating system, but may involve creating a new network interface. This can look like single sign-on, but uses the same network card in the background.
Can you have multiple A records in DNS?
You can do a lot with A records, including using multiple A records for the same domain to provide redundancy and fallbacks. Also, multiple names could point to the same address, in which case each would have its own A record pointing to the same IP address. The DNS A record is specified by RFC 1035.
Can two devices have the same hostname?
Question 1: Yes, it is possible for multiple devices on a network to have the same hostname. You can easily change the name of two computers on a network and they share the same hostname.
Can you run multiple websites from a single IP address?
IP-based virtual hosting is a method to serve different websites based on IP addresses. You can assign a separate IP address to each website on a single server.
What happens if a domain has two different A records?
2 answers. Yes you can. This is called circular DNS, and the browser just randomly picks one of these. It’s a widely used method to achieve cheap load balancing, but if a host goes down, users will still try to access it.
What happens if 2 devices have the same IP address?
For a system to communicate over a network, it must have a unique IP address. Conflicts arise when two devices are on the same network and try to use the same IP address. In this case, both computers cannot connect to network resources or perform other network operations.
Does each device have a different IP address?
Instead of your ISP assigning every device in your home a unique public IP address — you would need an additional IP address every time you bought a new computer, tablet, smartphone, games console, or anything else — it assigns you Your ISP usually assigns a unique IP address.
Can you have multiple PTR records with the same IP address?
While most rDNS records only have one PTR record, DNS doesn’t limit the number. However, it is generally not recommended to have multiple PTR records for the same IP address unless there is a specific need. A reverse DNS record that matches your banner is fine.
Can a Cname refer to multiple A records?
A CNAME record should always point to another domain name and never directly to an IP address. A CNAME record cannot coexist with another record with the same name. It is not possible to have both a CNAME and a TXT record for www.example.com.
