1. I have a delegated domain mydomainname.ru. I ordered the web-forwarding (mail-forwarding) service from you. What records should I enter into the DNS for everything starts working? - For the mail-forwarding service you should enter into the mydomainname.ru zone file a record: mydomainname.ru. MX 0 mf1.nic.ru. See also: description of MX-records - For the web-forwarding service for www.mydomainname.ru you should enter into the mydomainname.ru zone file a record: www.mydomainname.ru. A 194.85.61.54 - For the web-forwarding service for mydomainname.ru you should enter into the mydomainname.ru zone file a record: mydomainname.ru. A 194.85.61.54 2. I have a domain mydomainname.ru. My provider assigned a separate IP-address for my WWW. I want it to respond not only to www.mydomainname.ru, but also to mydomainname.ru. What records should I enter into the DNS? - If you want your server to respond to www.mydomainname.ru, you should enter into the mydomainname.ru zone file an A record: www.mydomainname.ru. A IP-มฤาลำ - If you want your server to respond to two names: www.mydomainname.ru and mydomainname.ru, you should enter into the mydomainname.ru zone file an A record: www.mydomainname.ru. A IP-มฤาลำ mydomainname.ru. A IP-มฤาลำ 3. My WWW is allocated at a provider and has a name www.mysite.myprovider.ru (or www.myprovider.ru/~mysite/). I registered a name mydomainname.ru for it. What should I do to make it respond to www.mydomainname.ru? What records should I enter into the DNS? There are several ways of solving this problem. Way 1.: - You should find out the IP-address, where your WWW is located, from the provider. For example, it is 1.2.3.4. - On primary, in the mydomainname.ru zone file enter an A-record for www.mydomainname.ru: www.mydomainname.ru. A 1.2.3.4 - Address your provider and ask him to change the settings of the web-server, maintaining your WWW. Way 2.: - On primary, in the mydomainname.ru zone file enter an CNAME-record for www.mydomainname.ru: www.mydomainname.ru. CNAME www.mysite.myprovider.ru. or, if your WWW is visible under the name www.myprovider.ru/~mysite: www.mydomainname.ru. CNAME www.myprovider.ru. - Address your provider and ask him to change the settings of the web-server, maintaining your WWW. 4. I have a domain mydomainname.ru. I adjusted the mail server on a host with an IP-address 1.2.3.4. What records should I enter into the DNS for everything to work? It is necessary to: - make up a name for it. For example, relay.mydomainname.ru. - enter the following records into the mydomainname.ru zone file: relay.mydomainname.ru.A 1.2.3.4 mydomainname.ru. MX 10 relay.mydomainname.ru. See also: description of MX-records 5. I have a domain mydomainname.ru. I would like to delegate a sub-domain info.mydomainname.ru. What records should I enter into the DNS for e verything to work? Way 1. If you ordered the primary and the secondary for the info.mydomainname.ru domain from your Provider (for example, primary: ns3.your-provider.ru, secondary: ns4.your-provider.ru), you have to enter the following records into the mydomainname.ru zone file: info.mydomainname.ru. NS ns3.your-provider.ru. info.mydomainname.ru. NS ns4.your-provider.ru. Way 2. If you administer the primary yourself, and it is called ns1.mydomainname.ru (IP-address 1.2.3.4), and you took the secondary from your provider ns2.your-provider.ru, you have to enter the following records into the mydomainname.ru zone file: ns1.mydomainname.ru. A 1.2.3.4 info.mydomainname.ru. NS ns1.mydomainname.ru. info.mydomainname.ru. NS ns2.your-provider.ru. Don't forget that it is necessary to indicate ns1.mydomainname.ru and ns2.your-provider.ru in the NS list of the info.mydomainname.ru zone file, that is, to enter records: info.mydomainname.ru. NS ns1.mydomainname.ru. info.mydomainname.ru. NS ns2.your-provider.ru. Way 3. If you administer the primary yourself, and it is called ns3.info.mydomainname.ru (IP-address 1.2.3.10), and you took the secondary from your provider ns2.your-provider.ru, you have to make the following records in the mydomainname.ru zone file: ns3.info.mydomainname.ru. A 1.2.3.10 info.mydomainname.ru. NS ns3.info.mydomainname.ru. info.mydomainname.ru. NS ns2.your-provider.ru. Don't forget that it is necessary to indicate ns3.info.mydomainname.ru and ns2.your-provider.ru in the NS list of the info.mydomainname.ru zone file, that is, to enter records: info.mydomainname.ru. NS ns3.info.mydomainname.ru. info.mydomainname.ru. NS ns2.your-provider.ru. ns3.info.mydomainname.ru. A 1.2.3.10 6. I have a domain www.mydomainame.ru with an IP-address 1.2.3.10. I registered a domain internet-name.ru. What should I do to make www.mydomainname.ru respond to www.internet-name.ru? What records should I enter into the DNS for everything to work? Way 1. In the internet-name zone file you have to enter a record: www.internet-name.ru. A 1.2.3.10 Way 2. In the internet-name zone file you have to enter a record: www.internet-name.ru. CNAMEwww.mydomainname.ru. 7. In my domain mydomainname.ru there is a host with an IP-address 2.3.4.5, where there are several services: www, ftp, dns. I want my host to respond to the corresponding names. What records should I enter into the DNS? You have several ways: Way 1.: For each service make up a name of the machine (for example, www.mydomainname.ru, ftp.mydomainname.ru, ns.mydomainname.ru) and enter corresponding A-records into the mydomainname.ru zone file: www.mydomainname.ru. A2.3.4.5 ftp.mydomainname.ru. A2.3.4.5 ns.mydomainname.ru. A2.3.4.5 Way 2.: Make up a basic name for the machine (for example basic.mydomainname.ru). Enter an A-record for it. For each service make up a name of the machine (for example, www.mydomainname.ru, ftp.mydomainname.ru, ns.mydomainname.ru) and enter corresponding CNAME-records into the mydomainname.ru zone file: basic.mydomainname.ru. A2.3.4.5 www.mydomainname.ru. CNAMEbasic.mydomainname.ru. ftp.mydomainname.ru. CNAMEbasic.mydomainname.ru. ns.mydomainname.ru. CNAMEbasic.mydomainname.ru. 8. I heard about "reverse" domains - what is that? Using reverse domains (reverse zones) IP-addresses are converted into host names. There are lots of servers (maintaining different services), adjusted in such a way, so that they check the presence of records about the host, to which they refer, in the direct and in the reverse zones. If a record in one of these is absent, access to the service from this host might be closed. If the provider assigned several IP-addresses to you from his network, than he is the one you should address about records in the reverse zone. That is, if the provider assigned an IP-address 194.85.61.42 to you un the 194.85.61.0/24 network, the record about your host (for example, www.mydomainname.ru) will be entered in the reverse zone 61.85.194.in-addr.arpa. The record will look this way: 42 PTR www.mydomainname.ru. 9. I heard about SPF-records. What is that and how to enter these records into the DNS? SPF (Sender Policy Framework) - is a technology, intended for checking the sender of e-mails. The domain administrator publishes conditions, which are met by all acceptable ip-addresses of sources of mail with the address of the sender from this domain. The accepting mail server verifies the compliance of the sending server's ip-address with conditions, set for the sender's domain. Result of the verification is taken into account when deciding whether to accept or decline a letter. At the moment SPF data publication is done in the form of a TXT record for the source-domain. A detailed description can be found on http://spf.pobox.com. 10. I wish to set up mail for my domain mydomainname.ru. on mail servers GOOGLE.COM. Which records should I add to DNS-servers to make it work? You should set up "ํ่" records, like the following: mydomainname.ru. MX 10 aspmx.l.google.com. mydomainname.ru. MX 20 alt1.aspmx.l.google.com. mydomainname.ru. MX 20 alt2.aspmx.l.google.com. mydomainname.ru. MX 30 aspmx2.googlemail.com. mydomainname.ru. MX 30 aspmx3.googlemail.com. mydomainname.ru. MX 30 aspmx4.googlemail.com. mydomainname.ru. MX 30 aspmx5.googlemail.com. Each record shall end up with a dot, as shown above. To confirm your domain ownership right you are also required to set up a "CNAME" type record, like the following: google่่่่่่่่.mydomainname.ru. CNAME google.com. where google่่่่่่่่ - your user ID indicated on domain setting page in mail service GOOGLE.COM. |
