You've clicked the "Register" button, the money's been deducted, the confirmation email has arrived, but when you type the address into your browser you get a blank page or a DNS_PROBE_FINISHED_NXDOMAIN error. This is exactly where most site administrators think the domain registration is broken, when the problem is actually somewhere else. Domain registration only creates a row in the registry; what brings the site up is connecting that row to your server.
Before paying, check domain availability properly
A simple search in the panel only shows the registry's current status. A domain that appears "available" might be in pendingDelete status; meaning the previous owner abandoned it and it's not yet registrable until the deletion period ends. If you register it right now, the money is refunded but you lose the domain and someone else snaps it up.
For a more precise check, use WHOIS:
whois example.com | grep -iE "status|expiry|registrar"If you see redemptionPeriod or pendingDelete in the output, hold off. .com domains usually stay in this state for 5 to 75 days and then become available. For Iranian domains, you should check the status through the complete guide to registering and managing .ir domains with an IRNIC ID, because IRNIC's rules differ from ICANN's and the IRNIC ID must be verified in advance.
Choose the extension based on use case, not price
The cheapest extension is almost always the most expensive option in the long run. The table below is what I see in practice:
| Extension | Best for | The catch that shows up late |
|---|---|---|
.com | General business, brand | Renewal is more expensive than initial registration |
.ir | Domestic audience, local trust | Requires IRNIC ID and documents |
.net | Infrastructure, technical services | Good availability, less competition |
.shop and similar | Online store | Renewal price is several times the first year |
If your main audience is inside Iran and you want to appear in Persian search results, .ir is the right choice. If you plan to later sell the site to a foreign market or build corporate email on it, go with .com. Here's where people make a mistake: they grab the cheap first-year extension, and in the second year when the renewal price triples, they abandon the domain and all the backlinks and brand credibility are lost.
Fill in owner information carefully
The domain registration form isn't like a site signup form. Every field goes to public WHOIS, and changing it later is costly and troublesome. Take three things seriously:
- Email: Provide an email you'll have access to for years. The ownership verification email goes to that address, and if you don't respond within 15 days, the domain goes into
clientHoldstatus and the site becomes inaccessible. - Name and address: For individuals, exactly what's on your identity documents. A mismatch causes the request to be rejected by IRNIC.
- WHOIS privacy: For
.comit's free almost everywhere and hides your personal information. For.irno such thing exists and the owner's information is public.
A point few people mention: if you're registering the domain for a client, don't put ownership in your own name. Later, transferring it requires the signature of the registered owner, and if your relationship sours, the domain becomes a hostage.
Why the site doesn't come up immediately
Domain registration and DNS activation are two separate steps. After payment, the domain is registered in the registry, but until you point the DNS records to your server, nothing happens. If you have a VPS, you need to create an A record:
example.com. 3600 IN A 203.0.113.45
www.example.com. 3600 IN CNAME example.com.The number 3600 is the TTL; meaning resolvers cache this value. If you change the IP later, it takes up to an hour to propagate everywhere. My recommendation is that before any IP change, reduce the TTL to 300 24 hours in advance. The full details of this process are in connecting a domain to a VPS; complete guide from A record to SSL.
The actual propagation time is usually between 10 minutes and 48 hours, depending on the previous TTL and ISP caches. If it still doesn't open after 48 hours, the problem isn't domain registration; it's DNS. With checking DNS records you can see what the records look like from the perspective of different servers and which ISP is still holding onto the old cache.
If you have dynamic subdomains
For services where each user gets a subdomain, creating records manually won't work. A wildcard record does the job:
*.example.com. 3600 IN A 203.0.113.45But be careful: a wildcard affects all subdomains, including those you'll want to manage separately later. If you create a more explicit record for a subdomain, that one takes priority. How to manage this case is explained in wildcard records and managing dynamic subdomains in DNS.
The cost nobody talks about
Domain registration isn't a one-time cost. It has an annual renewal, and if you forget to renew, the grace period is usually 30 days, after which you enter the redemption period whose cost is several times a normal renewal. For .ir these windows are shorter. The exact steps and how to rescue a domain are in domain renewal; complete guide to expiration steps and rescuing a domain.
My practical suggestion: turn on auto-renew and keep the card valid. If you don't want the card on file, at least set a reminder 30 days before expiration. I've seen 10-year-old domains fall into the hands of domainers just because nobody saw the reminder email.
And one decision you should make right from the start: should you get the domain and hosting from the same place or separately? If you're a beginner, get them together; support is one contact and record configuration is done automatically. If you have a technical team and want full control over DNS and migration, register the domain independently and manage DNS yourself. For serious projects, I choose the second option because the next migration happens without getting tangled up with the registrar's panel. If your site is hosted on Linux hosting, usually keeping them together is the fastest way to get the site up.
Frequently asked questions
Why wasn't a domain that was available registered after payment?
Because at the moment of registration, the registry rejected it. This happens when the domain was in pendingDelete status or someone else registered it seconds earlier. The money is usually refunded within a few business days, but you need to search for the domain again.
How long does it take for a domain to become active?
The registration itself in the registry is nearly instant, but DNS propagation takes between 10 minutes and 48 hours. This window depends on the records' TTL and how long ISP servers cache, not on the registrar's speed.
What documents are needed to register a .ir domain?
A verified IRNIC ID and identity documents matching the owner's name. For legal entities, the official gazette and company documents are also required. A mismatch between the owner's name and the documents is the most common reason for a request being rejected.
Can I transfer the domain to another registrar later?
Yes, provided that at least 60 days have passed since registration or the last transfer and the transfer lock (clientTransferProhibited) has been removed. Get the transfer code (EPP) from the current panel and enter it in the new panel.
Before anything else, check the auto-renewal status of your domains right now. It takes a minute and prevents losing years of brand credibility.
