What is a domain
Also known as: domain name, internet domain, co.il domain
Definition
A domain is your unique name on the internet, like example.co.il, rented for a set period through a registrar. Through DNS it points to your site and email.
Why it matters
Your domain carries your website, your email addresses such as name@yourbusiness.co.il and the logins of many services, so losing it can take all of them down at once.
Common mistakes
Letting a web designer or supplier register the domain in their own name.

Registry
ISOC-IL, which runs .il.
Registrar
An accredited registrar from ISOC-IL's list.
Registrant
The business, with an email address the owner controls.

Steps
The owner checks that the name is free with the WHOIS search on isoc.org.il.
She picks a registrar from ISOC-IL's list of accredited registrars.
Decision: She registers the name in the business's name, with an email address she controls, not the web designer's.
She turns on auto renew and the registrar lock, and puts the renewal date in the calendar.
She points the domain through DNS to the website and to the email service.
She gives the web designer access as a user, not as the owner.
The name is rented, so the one thing that must never lapse is the renewal, in the business's own account.
Illustration

Everything starts from the name. The directory, the site and the email all hang on it, so the renewal is the one date that must never lapse.
Definition
A domain name is a unique name registered for a period through a registrar, which the owner points, through DNS, to a website and to email. It stores nothing itself and can exist with no website at all. Three parties are involved: the registry runs the extension (for .il it is ISOC-IL, the Israel Internet Association), the registrar sells and manages your registration, and the registrant is you, and should be the business. Read www.example.co.il from the right: "il" is the country extension, "co" the category, "example" the chosen name, and "www" a subdomain the owner creates for free. A URL is the full address of one page, such as https://www.example.co.il/contact, and the domain is only one part of it.
Why it matters
A domain is rented, never owned outright, which explains auto renew, expiry and transfers. Under .il anyone, a person or a company, Israeli or foreign, may register under co.il and org.il with no local presence, while ac.il is for academic institutions, gov.il for government bodies and muni.il for local authorities. Registration goes through accredited registrars, and a WHOIS search on isoc.org.il shows whether a name is free. Disputes over a name have their own tracks: ISOC-IL's IL-DRP for .il and ICANN's UDRP for generic domains.
Improvement tips
- Register the domain in the business's name, from an email address the owner controls.
- Turn on auto renew and the registrar lock, and keep the renewal date in the calendar.
- Choose the extension by your market: co.il for customers in Israel, and .com first only if you sell mostly abroad.
- Protect the registrar account with two step login, because whoever controls it controls your site and email.
Common mistakes
- Letting the domain expire because the renewal notice went to an old email address.
- Confusing the domain with the website or the hosting, which are separate services.
- Picking a name close to someone else's trademark, which invites a dispute.

Hosting is a service that rents you space on a server connected to the internet all the time, so your website is available to every visitor.

Anna
Beautician
After I finished a cosmetology course at a leading company, I was confused. I didn't know how to open a business, what to sell from home, or how to bring in clients. Since I reached out to Mobius, everything has changed. We built an organized plan with clear steps and no unnecessary risks. Today I see results, and I'm growing and developing every month.

When I finished a massage course, I imagined a different world. I found out it's a hard field, and financial stability isn't easy to find. When I came to Mobius, something changed. We started an organized process and built a business plan. Without Mobius? I probably would have given up. Today I believe in myself and in my own path.
