Creating DNS Records
General
The Domain Name System (DNS) is one of the most important services in the IT network. It's main task is to respond to requests for name resolution.
In analogy to request the contact information to the DNS from a host name (the name of a machine noticeable for people on the internet) for example www.example.org, as a response for the associated IP address (the "Port Number" on the Internet) for example, an IPv4 address like to call 192.12.0.10 or an IPv6 address as 2001: db7: 83d3: 8d1: 1329:8 a2f: 073:4773
Creating DNS-Record
In the EUserv customer center, you have the possibility to create the different types of DNS records.
Choose your domain of contract for which you want to create the DNS records.
Once you have selected your domain contract, now click "DNS-Verwaltung" under Domain.
Creating A-Record
Now you can see the surface of the DNS records. Here, you can create the DNS record. Make sure that in "Domainname:" the selected desired domain is displayed.
In "aufzulösender Wert (Hostname, z.B. "www"):", enter the desired value. A "*" stands for a wildcard entry, which means that all entries will be redirected prior to your domain (e.g., xyz.meinedomain.de) and you have to specify on the IPv4 address. In this example we use the IPv4 address 127.0.0.1 (note: the IPv4 address 127.0.0.1 does not work, but is the local host address of each computer and is used here only as an example). Now enter xyz.meinedomain.de, to reach the corresponding server (meinedomain.de) of the IPv4 address 127.0.0.1. Thus we can ensure that the visitor will be redirected to the server that you have defined under 127.0.0.1. (e.g., for landing pages).
Enter in this field the famous "www", so visitors who enter www.meinedomain.de will successfully redirected to the defined server under www.meinedomain.de. However, should a visitor leave out the "www", so he will not come to your server and land on an error page.
In "Ziel (Hostname, IPv4-Adresse usw.):" you must enter the desired IPv4 address, that to be forwarded (eg 127.0.0.1).
For "TTL (in Sekunden, default 86400):" (is automatically set to 86400) and "Priorität (nur MX und SRV):" (from A records not required), you don't have to make any entries.
Your customer service center should now look like this:
or so:
Click save after you create an entry, to save your input. Twice DNS-Records should be deleted.
Creating AAAA-Record
As the Internet world grows faster, more and more IPv4 addresses are required but only available in limited quantities. And they have created the IPv6 successor.
In order to conduct such an IPv6 address further, it requires an extra record, since the A-standard here does not work anymore. For it serves AAAA.
The AAAA record has the same function as an A record, but for forwarding to IPv6 addresses stringently required. For an AAAA record, please take the input analog front to an A record.
Creating MX-Record
An MX record is responsible for the information, among which address a mail server to a domain or subdomain is accessible (MX=Mail Exchange).
Therefore, to reach the messages matching your domain and your mail server. To a possible disturbance at the mail server or a wrong subdomain in the email address against to act, it is advisable to set several MX-Records and to assign different priorities.
With the MX record, you can define which messages are routed where, so that different subdomains are possible (mail@meinedomain.de - the part after the @ is defined by the MX record).
A mail server on your domain wants to send a mail. Check the MX record with the lowest priority (e.g., eins.meinedomain.de, priority 10) and then, if the first is not reachable, try the other MX records (e.g., two. meinedomain.de, priority 50th ..). Therefore, a mail that the first mail server could not be delivered. The second sent and the mail addressed to you will not be lost.
Please note that it is imperative to specify a domain because at MX records can not be used with IP addresses and any wildcards ("*")!
Restore Defaults
You should create a DNS records that do not achieve the desired result, or even your domain should no longer be available, so you can reset the DNS records automatically to customer service center.
