Can one host name have multiple IP addresses?

Can one host name have multiple IP addresses?

The hosts file allows no way of distinguishing different “record types” for its resolution. So for hostname to IP address mapping, you only get one IP address per hostname (but multiple hostnames could resolve to the same IP address, which is the opposite).

Why would a host have 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.

How do I add multiple IP addresses to a host file?

Easy to setup, please follow the instruction:

1. install dnsmasq.
2. edit /etc/resolv.conf and set “nameserver 127.0.0.1” as a first DNS.
3. add normal DNS as alternative (google one for example) “nameserver 8.8.8.8” as a second line.
4. make sure two required records are in your /etc/hosts file.

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.

What does an A record contain?

The “A” stands for “address” and this is the most fundamental type of DNS record: it indicates the IP address of a given domain. For example, if you pull the DNS records of cloudflare.com, the A record currently returns an IP address of: 104.17. 210.9. A records only hold IPv4 addresses.

Can you have 2 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.

Is the host name the same as the IP address?

The alias hostB specifies the first address, and the aliases hostC and host-C specify the second address. LSF uses the official host name, hostA, to identify that both IP addresses belong to the same host. “The format of LSF_CONFDIR/hosts is similar to the format of the /etc/hosts file on UNIX machines.”.

How to assign multiple IPs to one entry in hosts file server?

There are 2 IPs (primary and secondary) to the database from the web server. How can I setup my /etc/hosts file so that if the primary IP is not available then the secondary IP will be used?

How to add multiple hosts in / etc / hosts?

I have just added two domains to my web server and I just wondered if I need/must add the two new domains to the /etc/hosts file? A t the moment I have got: $More /etc/hosts ::1 localhost localhost.curentwebsite.com 127.0.0.1 localhost localhost.curentwebsite.com 192.168.0.150 marvin.curentwebsite.com marvin 192.168.0.150 marvin.curentwebsite.com.

Can you assign multiple IP addresses to one name?

Most DNS will provide what’s called a “Round Robin” if you assign multiple A records to the one name in the zone. What it would do then, is the first request comes through would receive 192.168.244.128, the next would receive 192.168.226.129, so on and so forth.
