DNS Zone

This service allows you to define what is called a DNS zone. These are the IP addresses of your sites and the mail servers of your site.
If you have a domain with us, then this service is automatically available.

How to use this service

To use this service, you must activate the DNS zone in your manager and associate your domain with the DNS servers for that zone.
To do this, connect to your Manager Click on "Activate DNS Zone"
Once the service is activated, you can benefit:

Round Robin

You can manage multiple type A or AAAA fields, this means that you can spread the load of your website on multiple servers by specifying multiple IP addresses

The advantage is that when your clients log on to www.onvousheberge.fr, their browser will choose randomly from among a list of IP addresses, which will spread the load on your servers.

Wildcards

You can define what are known as wildcards, so you can operate in one http://www.onvousheberge.fr, http://mail.onvousheberge.fr, http://blog.onvousheberge. fr ... using a single definition: *. onvousheberge.fr in the dns

SPF fields

This guarantees that the remote mail servers that you have are allowed to send mails. It is mainly used for preventing SPAM.

( onvousheberge.fr. IN SPF "v=spf1 ip4:192.168.1.200 ~all" )

Here 192.168.1.200 is the server that is allowed to send mails in which the sender est@onvousheberge.fr

TXT fields

For example the TXT field will allow you to define the public keys (Domainkeys) used to verify the signatures of mails that you create, it is a free technology of the SPF.

(gamma._domainkey.onvousheberge.fr. IN TXT k=rsa; t=y; p=DS4GDZu6ZRVh8tgDS64GVg6sd7F9D9D....Hfuj7G9hF67SEGG3G)

Redirects

Simply redirect the address of your choice:
http://ovh.onvousheberge.fr -> http://www.ovh.com

To do this go to your Manager Click on "Web Redirection"

DynDns fields

If your computer is connected to the Internet but the IP address changes dynamically, you can define a DynDns field that updates itself automatically when your computer changes address.
http://chezmoi.onvousheberge.fr/ and always refer to your computer, even if its IP changes.

MX fields

The classic fields such as the MX allows you to define remote mail servers, and which one will receive the mails.

CNAME fields

The CNAME fields are aliases allowing you to regroup your definitions.

(blog.onvousheberge.fr. IN CNAME www.onvousheberge.fr.)

blog.onvousheberge.fr will behave identically to the definition of www.onvousheberge.fr

SRV Fields

They allow you to specify the server address and port to use for a given service. This is an extended version and more generic field of MX.

For example, to specify that servers server1.onvousheberge.fr and server2.ouvousheberge.fr, port 143 are IMAP servers for your domain name onvousheberge.fr, simply specify
_imap._tcp.onvousheberge.fr. IN SRV 10 0 143 server1.onvousheberge.fr.
_imap._tcp.onvousheberge.fr. IN SRV 20 0 143 server2.onvousheberge.fr.

These definitions allow customers to use mail set simply by specifying the email and password for example.

NAPTR Fields

They allow you to specify the public services that you distribute under your domain.

For example, to specify publicly that, under the domain onvousheberge.fr you provide 4 services such as a music server (DAAP), a web server (http), file server (FTP) server for telephony (SIP ). Just declare these 4 fields NAPTR:

• onvousheberge.fr. NAPTR 10 100 "S" "http+I2R" "" _http._tcp.onvousheberge.fr.
• onvousheberge.fr. NAPTR 20 100 "S" "ftp+I2R" "" _ftp._tcp.onvousheberge.fr.
• onvousheberge.fr. NAPTR 20 100 "S" "sip+I2R" "" _sip._udp.onvousheberge.fr.
• onvousheberge.fr. NAPTR 20 100 "S" "daap+I2R" "" _daap._tcp.onvousheberge.fr.

The customer can then inform the server (address and port) of each of these services using a supplementary query SRV

You can also publish additional data such as email, SIP account associated with a domain:

• 1.6.7.1.0.7.9.9.8.3.3.e164.arpa. IN NAPTR 102 10 "u" "E2U+email" "!^.*$!mailto:support@ovh.net!i" .
