General Questions

I already have a domain registered using someone else. Can I still use Nettica for DNS?

Yes. You do not need to register or transfer your domain to Nettica to use our DNS services.

What are the names of Nettica's DNS servers?

Nameserver IP Address
dns1.nettica.com 64.94.136.11
dns2.nettica.com 64.237.45.34
dns3.nettica.com 64.94.136.13
dns4.nettica.com 69.41.170.223
dns5.nettica.com 212.100.247.15

Can I have more than one domain pointing to the same IP address?

Yes. However, DNS service is on a per-domain basis, not per IP Address. If you are interested in hosting multiple domains using the same IP address, we recommend you use a server (Windows Server, Linux, Unix, Apache, etc) that supports multiple virtual hosts. If you are hosting using something like Windows XP Professional, you can use URL forwarding and masking to support multiple domains on a single IP address.

All of my domains have the same configuration. Do you have anything that makes this setup easier to manage?

Yes. With Bulk DNS services, you can set up a template to create and manage your domains. Templated DNS management is only available to Bulk DNS customers.

What is an internationalized domain name? What support do you have for it?

An internationalized domain name allows additional characters in the domain name besides the standard ASCII character set. For European countries this includes accented characters, while for Asia it provides much of the country specific character set. International domain names use a special encoding method to identify them to browsers, email clients, and other programs. Nettica supports international domain names in our DNS services.

Primary DNS

How do I change my DNS to use Nettica? How long does it take for the change to happen?

Before beginning, it is recommended that you first purchase DNS services from Nettica, and configure the DNS. This will ensure a smooth transfer in the Internet's Domain Name System.

Login to your current registrar's control panel and find the area in their control panel for configuring the name servers. With GoDaddy you might see their name servers listed as domaincontrol.com, Network Solutions worldnic.com, etc. Edit the list of name servers and set them to:

Nameserver IP Address
dns1.nettica.com 64.94.136.11
dns2.nettica.com 64.237.45.34
dns3.nettica.com 64.94.136.13
dns4.nettica.com 69.41.170.223
dns5.nettica.com 212.100.247.15

and then save the changes. Typically the IP address is not required when setting the name server list, but occassionally with some ccTLDs it might be needed.

The changes will go into effect on your domain immediately. However, it can take up to 48 hours to update across the Internet.

How long does it take for a Nettica DNS entry to change?

Changes you make using our management interfaces are real-time. Once you click OK the changes have been made. However, because DNS is a caching system, it can take up to an hour for caching DNS servers to expire their entries (fore precisedly, it takes the TTL of the record, and the default TTL is one hour). If you are about to make a DNS change, we recommend that you not ping the address just before the change, or rest assured you will have to wait until the timeout to see the update.

How many DNS entries can I have per domain?

There is no built-in limit to the number of DNS entries per domain with Nettica. However, if you have more than 100 DNS entries for a single domain we may contact you to help you simplify your DNS setup. We support wildcard records which greatly simplfies many configurations. Your DNS may not exceed 500 entries without contacting support and agreeing to the overage charges.

Do you support the Sender Policy Framework (SPF) and Sender-ID?

Yes. SPF and Sender-ID use DNS Text (TXT) records to define which email servers are permitted to send email on your behalf. Support for TXT records are included in our primary DNS services. While SPF is not a cure-all for spam, it does prevent spoofers or virus' from destroying your site's reputation, and is becoming widely adopted by major ISPs around the world.

Do you support round-robin DNS entries?

Yes. To enable round-robin DNS simply create two identical entries that only differ by IP address.

DNS round-robin configuration

Typically, only A records are used for round-robin. You cannot specify multiple CNAME records to point to different hosts. However, you can use the CNAME to point to multiple A records and achieve the same effect. (See above.)

You should only use round-robin DNS if you have static IP addresses. The Nettica DNS manager supports round-robin DNS, but third-party clients may not. Avoid dynamic update clients if you are using round-robin DNS.

Do you support wildcard DNS entries?

Yes. To specify a wildcard DNS entry, create the entry “*.example.com” and give it an IP address. Named entries take precedence over wildcard entries. (See below.)

DNS wildcard configuration

How do I setup URL forwarding? What is the difference between forwarding and masking?

To manage your URL forwarding go to the DNS management page for your domain and click the "New Forward" button. Enter the subdomain you would like to forward (eg, "webmail.example.com", etc), and the HTTP URL you would like to forward the request to and click the OK button.

Configure URL forwarding

Forwarding redirects you straight to your site (301 or 302), whereas masking places your site inside a frame. Masking provides a friendly name that can be seen in the address bar. However, the drawback to masking is that most search engines have a harder time indexing your site, using your friendly URL. Unlike forwarding, you cannot mask to an https: URL. These are some of the reasons Nettica offers both forwarding and masking services.

In addition to forwarding, masking, and 301 redirects, you can also specify whether or not to route all requests to the exact URL you specify, or to have us automatically reparse the URL to it's final location (this is the default behavior).

For example:
If you type or click the link http://www.domain1.com/support and you forward your request to http://www.domain2 .com, then reparsing them would bring the request to http://www.domain2.com/support. If you click “Redirect to the exact URL”, they would instead go to http://www.domain2.com.

Do you support rebranding your primary DNS service?

For step by step instructions for rebranding our primary DNS service, see our knowledge base article on it.

Secondary DNS

How do I set up Nettica to be my secondary DNS service provider?

To setup Nettica as the secondary DNS service provider there are three steps involved:

  1. At your Primary DNS service provider and add two additional NS records (Name Server records) for dns2.nettica.com and dns4.nettica.com
  2. Configure your secondary DNS service at Nettica by entering the name and IP address of your master DNS server (usually the primary DNS server). This will allow us to accept zone transfer requests from your master DNS server. Click on "CHECK STATUS" to see if this worked properly.
  3. Add dns2.nettica.com and dns4.nettica.com to this list of Name Servers for your domain. You do this at your domain registrar.

How do I enable zone transfers to Nettica's DNS servers using Bind?

Add the following to your /etc/named.conf file:

options {
// allow transfers to Nettica's DNS servers
allow-transfer { 64.237.45.34; 69.41.170.223; };
};

If you are using a tool to manage your named.conf file, use it to make the changes to ensure your changes do not get overwritten. You only need to change the allow-transfer option; you may leave the others as they are.

How can I verify the zone transfer worked?

Go to a command prompt and issue the following commands:
c:>nslookup - dns2.nettica.com
Default Server: dns2.nettica.com
Address: 64.237.45.34

> set type=all
> example.com
Server: dns2.nettica.com
Address: 64.237.45.34
...

At this point, your SOA information will come up if the zone transfer worked. If you receive an error, then it has not yet completed (wait 15 minutes for the initial transfer or a forced refresh).

secondary dns configuration

Alternatively, simply go to the secondary DNS management page for the domain and click "CHECK STATUS" as seen above.

How can I force a zone refresh?

You can force a refresh by going to secondary DNS management page for your domain and clicking on the "FORCE REFRESH" button. It can take up to 15 minutes for the refresh to complete.

How do I rebrand your secondary DNS service?

To rebrand our secondary DNS service, go to your domain registrar. Create two new custom name servers for your domain, using the IP addresses dns2.nettica.com and dns4.nettica.com. You then use ns2 and ns4.yourdomain.com when adding NS records. It is the easiest way to customize our DNS service.

Do you have any APIs for programmatically managing secondary DNS zones?

Yes! We have both a SOAP API, as well as an HTTP API to manage secondary DNS zones. These APIs let you create, delete, and list your secondary DNS zones. To create a zone using our HTTP API, you simply send a HTTP GET request using CURL (or similar program) as follows:

https://www.nettica.com/DNS/DnsApi.aspx?U=user&PC=passclear& CMD=createsecondary&D=domain&M=master&MIP=ipaddress

These APIs are only available to our Bulk DNS customers.

Dynamic DNS

What is the difference between static and dynamic DNS?

The DNS system (a series of caches) “remembers” recently used IP addresses for a certain period of time. Usually a static DNS entry expires within an hour or two. A dynamic entry expires in a matter of minutes. When those entries expire, they must query a domain’s primary or secondary DNS server in order to get the new address. Although there may be an immediate change, it may not be “visible” until the entry expires and is refreshed. The time-to-live (TTL) is a term that measures how much time elapses before a cache entry expires. Static DNS has a long TTL, while dynamic DNS has a short TTL.

How long does it take for a Nettica dynamic DNS entry to change?

If you add or remove a dynamic DNS entry, the change may take up to an hour before you see it reflected across the Internet. If you are changing the IP address, the change will take a minute.

Which dynamic DNS clients support Nettica's DNS Service?

The following dynamic DNS clients support Nettica's dynamic DNS service:

Dynamic DNS Clients Platform
Nettica DNS Manager Windows
Nettica DNS Manager for Yahoo Widgets 3.0 OS X and Windows
DirectUpdate 4.0 Windows
DynSite Windows

I have a dynamic IP address. Why can't I use your reverse DNS service?

Reverse DNS services require your ISP to delegate reverse DNS lookups to our DNS servers. Since your IP address is dynamic and is derived from a pool, the ISP will not delegate that control to our servers. If you have a static IP range, then the ISP should be able to delegate the reverse DNS.

Reverse DNS

Do I have to use your regular DNS service to use your reverse DNS service?

No. Unlike some other companies, we do not force you to use our forward DNS service to take advantage of our reverse DNS services. You will, however, find our standard and bulk DNS services competitively priced.

What do I have to do to setup my reverse DNS?

Unlike forward DNS service where you make changes with your domain registrar, you must contact your ISP and request that they delegate reverse DNS for your IP block to our DNS servers. For more information see our tutorial on setting up reverse DNS.
