For an Irish audience, .ie signals a connection to Ireland. A .com may suit a broader audience. Check availability and compare registration and renewal prices separately.
Start with your customers
Your web address should be easy for a customer to read, remember and type. For a business serving Ireland, a .ie address is a natural option. If you expect customers in several countries, a .com is also worth considering.
There is no universal winner. Choose the address that fits how you introduce the business and where you want people to find you.
Understand .ie eligibility
The .IE registry requires evidence of identity and a connection to Ireland. An active Irish company CRO number can support an application. The registry publishes document options for individuals, businesses and other applicants.
You do not need to assume that company incorporation is the only way to qualify. Read the registry’s current document requirements for your situation.
Check each domain on its own
An available company name does not mean its matching domain is available. Likewise, registering a domain does not register a company. Check the exact address you want with a domain provider such as hoster.ie.
If you want more than one extension, check each one. Avoid buying many variations without a reason; focus first on the address you will actually use.
Compare more than the first year
Look at the registration price, renewal price and final payable total. Check whether email and website hosting are included or purchased separately. Keep the domain account under your control, use a secure password and plan for renewals.
Before ordering, read the spelling one more time. A short, clear name usually matters more than a clever abbreviation that needs explaining.
Test the address in real customer situations
Put two fictional addresses on the same sample invoice: alderline.ie and alderline.com. Read each aloud over a call, type it into a short email address and ask a colleague to write it from memory. Record mistakes instead of judging only how the address looks in a logo. Neither example is a checked or available domain.
Consider which audience you serve today and which you expect to serve later. Buying more than one extension may be useful if you have a clear purpose and an ongoing budget. It also creates multiple renewals and accounts to manage. Decide which address will be primary before commissioning a website.
Compare ownership and ongoing costs
| Question | Why it matters |
|---|---|
| Who is the registrant? | The correct person or organisation should control the domain |
| What is the first-term total? | A promotion may apply only to initial registration |
| What does the next renewal cost? | You need a continuing budget for the address |
| What is included? | Domain, hosting, email and support may be separate services |
| How is renewal handled? | Contact details, payment and responsibility need an owner |
Request comparable final totals for the same period and tax treatment. Save the provider's actual quote with its date. Our domain-cost guide shows a hypothetical calculation, not a live price list.
Join the domain decision to the name decision
Use the domain suggestion tool once you have a shortlist. It creates possible .ie and .com addresses; the linked hoster.ie search is where you check the exact address. A domain suggestion should not be described to a partner as a confirmed reservation.
For .ie, read the evidence guide and the registry's current applicant requirements. Keep proposed company-name approval, domain availability and trade-mark research as three distinct decisions. If you buy both extensions, organise the redirects, email use and renewal responsibility consistently.
