The domains maktabat-homs.sy and maktabat-homs.com look like one name with two endings, but two entirely different organisations stand behind them. The first is run by Syria’s national registry, requires documents to book, and can’t complete a chain today. The second is run by Verisign, can be registered by anyone from any country without documents, and moves between registrars under ICANN’s policy. So the extension isn’t decoration at the end of a name; it decides who sets the rules for your domain for its whole life. This article explains how extensions work from the root down to your name, where they differ, and how to choose between them.
01From the root to your name
DNS is an upside-down tree. At the top is the root zone, published by IANA under ICANN’s oversight, which today holds more than 1,400 extensions. The root zone stores no domains at all; for each extension it only stores the servers responsible for it. Each extension’s servers in turn store, for every domain beneath them, the name servers that answer for it. That is how a query for maktabat-homs.sy travels from the root to the .sy servers, and from there to the domain’s own name servers.

Behind every extension are four roles people often confuse, the most important being the , which owns the extension’s database, and the you deal with:
| Role | What it does | Example |
|---|---|---|
| ICANN and IANA | Run the root; ICANN sets policy for generic extensions and accredits their registrars | The domain transfer policy and its 60-day rule |
| Registry | Runs the extension’s database and servers, and sets its rules and wholesale price | Verisign for .com, and the national body responsible for .sy |
| Registrar | Sells you the name and passes your commands to the registry: register, renew, transfer, update | Illevante, an accredited registrar for the national domain |
| Registrant | Holds the right to the name for the registration term | Your company, or you personally |
02Types of extensions
IANA sorts extensions into categories, each with its own rule-maker:
| Type | Examples | Who sets the rules | Who registers |
|---|---|---|---|
| Classic generic | .com, .net, .org, .info | The registry, under contract with ICANN | Anyone, from any country |
| New generic | .shop, .tech, .app, .clinic | The registry, under contract with ICANN; some with special terms | Usually anyone |
| Sponsored | .edu, .gov, .mil | A sponsor for a specific community | Only those who prove they belong |
| Country code | .sy, .de, .uk, .eu | A body in the country itself, outside ICANN contracts | Per each country’s rules |
| Country code in a national script | .سورية | The same national body | Per its rules |
The classic extensions are the oldest, and after 2013 hundreds of new generic extensions were added, named after fields, cities and brands. ICANN opened a new application round between April and August 2026, so expect more extensions in the root over the coming years. are two-letter codes for each country or territory, each with its own independent policy.
Some new extensions carry technical rules their buyers don’t expect. The .app and .dev extensions, for example, are on the HSTS preload list built into browsers as a whole, so a browser will only open a site on them over HTTPS. If you register one of these, set up an SSL certificate before you publish the site.
03The national .sy extension
Syria’s code is .sy, and according to the IANA database it is managed by a national body, the National Authority for Information Technology Services (NAITS), which also runs the Arabic-script extension .سورية. Under .sy sit second-level extensions for each category, and the national registry sets the terms for each one. Illevante sells 16 national extensions, and these are their terms as the booking requires them:
- .sy and .me.sy: The first for any individual or organisation, the second for individuals, with the basic booking documents: a copy of ID, a working mobile number and email address, and a home address.
- .com.sy, .co.sy and .biz.sy: For holders of a sole-trader commercial register or a valid trade licence.
- .edu.sy, .school.sy, .teacher.sy and .stud.sy: For educational institutions and their members, with the institution’s licence or a valid proof of membership.
- .tv.sy, .news.sy and .info.sy: For media organisations licensed by the Ministry of Information.
- .net.sy: For networks and internet service providers.
- .org.sy, .gov.sy and .name.sy: For organisations with a licence or notice of incorporation, for government bodies with an official letter, and for individuals under their own real names only.
At Illevante the national domain is booked with a WhatsApp message to Illevante’s line, for one to 10 years, and it renews at the same price it was booked at. On the technical side, watch two things. First, the .sy delegation in the root is not signed with DNSSEC as of October 2026, so no chain of trust reaches your domain however you sign its zone. Second, its registration data is looked up on the national WHOIS server, whois.tld.sy.
# No answer: the extension isn’t signed in the rootdig +short DS sy.# An answer with numbers: a DNSSEC chain of trust starting at the rootdig +short DS com.# Registration data for a national domain, from its serverwhois -h whois.tld.sy dar-hasakah.sy
04Rules that differ by registry
When you choose an extension, you accept all of its registry’s rules. These are the main differences between a generic extension and a country one:
| Rule | A generic extension such as .com | A country extension such as .sy |
|---|---|---|
| Who may register | Any person or organisation, from any country | Depends on the second-level extension and its documents |
| Maximum term | 10 years | 10 years when booked through Illevante |
| Transfer between registrars | ICANN policy: an EPP code, and a year added to the term | The national registry’s rules |
| DNSSEC | Supported; .com has been signed since 2011 | Not available: the delegation is unsigned |
| Registration data | RDAP, the official source in place of WHOIS since January 2025 | The national WHOIS server |
| Geographic effect in Google | Neutral | A signal of a Syrian audience |
Even among generic extensions the rules vary. The .co registry, for instance, hasn’t accepted registrations longer than 5 years since its management moved to CentralNic in October 2025. Some country extensions require a link to the country: .eu for EU citizens and residents, .us for those with a genuine connection to the United States. And generic extensions in regulated fields, such as finance and health, require you to declare at registration that you hold the licences the field demands, and may be reviewed if someone complains.
Support for Arabic names varies too: an extension accepts them if its registry has published an Arabic script table with IANA, and many haven’t.
05Price: the first year isn’t the whole story
The registry sets each extension’s wholesale price, the registrar adds its own cost, and generic extensions carry ICANN’s yearly fee, which is included in the prices Illevante shows. Three patterns make next year’s invoice differ from today’s:
- A first-year promotion: Many new extensions sell at a promotional price in their first year, then renew at the regular price, which can be several times higher.
- Premium names: Some registries classify short names or common words as premium names with a higher price, and their renewals may stay higher too.
- Wholesale price changes: Some registries’ contracts allow them to raise prices periodically, so the renewal price itself changes over the years.
So work out the cost over five years: the first-year price, then four renewals at the regular price. And if the extension suits you, registering for several years at once fixes the price for the years you’ve paid.
06Extensions and search engines
This is where myths pile up, while the facts are few and clear:
- A country extension is a geographic signal: Google treats a country extension, such as .sy, as a strong signal that the site targets that country’s audience. That helps you in search results inside Syria, but it doesn’t put you in first place on its own.
- Generic extensions are neutral: Google gives no ranking advantage to a generic extension, old or new, and a keyword in the extension, such as .shop or .tech, doesn’t help you.
- Some country codes count as generic: Google treats some commercially popular country extensions, such as .io, .co, .me and .tv, as generic, so it doesn’t tie them to their country.
- No country-targeting setting: Google removed the target-country setting from Search Console in 2022. So if your site is on .com and targets Syria, the signals are the content and its language, hreflang tags, a local address, and links from Syrian sites.
The server’s physical location is a weak ranking signal, but it sets the latency your visitors get, and that is what they actually feel.
07Before you decide
These are problems we run into with extensions chosen without checking their rules:
- ProblemYou enabled DNSSEC on a .sy domain and resolvers don’t validate it
- FixThe delegation above your domain is unsigned, so resolvers treat your zone as unsigned. Rely on HTTPS and CAA records to protect your site until the national registry signs its extension.
- ProblemThe renewal price doubled after the first year
- FixThe promotion ended. Compare the renewal price before registering, or register for several years if the extension suits you.
- ProblemYour .com site shows up for searchers outside Syria more than inside
- FixA generic extension is neutral. Add local signals: Arabic content, hreflang tags and a Syrian address, or make .sy the primary domain for your audience at home.
- ProblemA national second-level booking was rejected
- FixUsually missing documents: .com.sy needs a commercial register, .edu.sy an educational licence, and .gov.sy an official letter.
The practical way to choose: define your audience first, then read the extension registry’s rules before its price, then work out the five-year cost. And before registering, look the name up with the WHOIS lookup tool on Illevante’s website to see its status and expiry date if it’s taken, with a signed PDF report. We cover the criteria for choosing the name itself in a separate article on the blog.
