Domain names: how they work, choosing a name, .co.ke vs .com, registering, renewing and protecting your domain

A domain name is your address on the internet: safaricom.co.ke, kra.go.ke, jumia.co.ke, marzleytechsolutions.co.ke. It's what customers type, what appears on business cards and in email addresses (info@yourbusiness.co.ke), and it's a big part of looking professional and being found. A domain is separate from hosting: the domain is the address, hosting is the house where the website lives. This unit explains how domains work, how to choose and register one, Kenyan options like .co.ke, and how to avoid the common (and costly) mistakes of losing a domain.

Domains, DNS and hosting

You rent a domain from a registrar (usually yearly), point it with DNS to your hosting, and visitors arrive at your website. You can move hosting without changing your domain; that's why owning your domain matters.

Parts of a domain

https://shop.mamamboga.co.ke/products
        │    │        │  └── TLD (country code): ke
        │    │        └───── second level under .ke: co (commercial)
        │    └────────────── the name you register: mamamboga
        └─────────────────── subdomain: shop (you create these freely)

• TLD (top-level domain): the ending. Generic TLDs: .com, .org, .net, .info, .africa, .shop, .tech. Country-code TLDs: .ke (Kenya), .ug, .tz, .uk.
• Subdomains (shop., portal., blog.) are free once you own the domain.

Kenyan domains

Kenya's domains are managed by KENIC (Kenya Network Information Centre) and sold through accredited registrars:

Some second-level domains require documents; registrars will tell you what's needed.

.co.ke or .com?

Many businesses register both (and point one to the other) to protect their brand. If you target Kenyan customers, .co.ke is an excellent choice.

Choosing a good name

• Short, easy to say and spell: test by saying it over the phone.
• Avoid hyphens and numbers (people forget them: "is it 4 or four?").
• Match your business name, or describe what you do + location: nakurudental.co.ke.
• Check it's not someone else's trademark.
• Check social media handles are available too, for a consistent brand.
• Don't make it so specific you outgrow it (nairobi-phone-repairs if you'll expand to Mombasa).

Check availability on any registrar's search box. If taken, try .ke, .co.ke, .com, .africa, or small variations.

Who's who: ICANN, registries and registrars

Registering step by step

1. Search for the name at an accredited registrar (for .ke, choose a KENIC-accredited registrar; many Kenyan hosting companies are).
2. Add it to the cart; choose the registration period (1 year or more).
3. Enter registrant details accurately: the business or person who should own it, a working email and phone. This is how ownership is proven later.
4. Pay (many local registrars accept M-Pesa).
5. Set name servers (your host's) or manage DNS at the registrar.
6. Turn on auto-renew and 2FA on the registrar account.

Renewals and expiry

• Domains are rented for a period; you must renew before expiry.
• After expiry there's usually a grace period where the owner can renew (sometimes with a fee), then a redemption period (expensive to recover), then the domain is released and anyone can register it.
• Expired domains break your website and email, and can be grabbed by others (sometimes to resell to you, or to host scams using your old reputation).
• First-year prices are often promotional; check the renewal price.

Ownership, transfers and WHOIS

• The registrant listed is the legal holder. Freelancers and developers should register clients' domains in the client's name and email, and hand over login details. A common painful situation: the developer who registered the domain disappears and the business can't renew or move it.
• Transfers between registrars use an EPP/auth code from the current registrar; the domain must usually be unlocked and not recently registered or transferred (many TLDs have a waiting period after registration or transfer).
• WHOIS/RDAP shows registration information (registrar, dates, name servers); personal details are often hidden by privacy rules or a privacy service.

Protecting your domain

1. Registrar account: strong unique password + 2FA.
2. Auto-renew with a valid payment method, and calendar reminders a month before expiry.
3. Keep the registrant email address working (on a different domain, e.g. Gmail, so you can still receive renewal notices if your own domain's email breaks).
4. Enable registrar lock (transfer lock).
5. Register for multiple years for important domains.
6. Keep records of the registrar, login owner and renewal date in your business records.
7. Watch out for "domain renewal" scam letters/emails from companies you didn't register with.

Subdomains and email

Once you own yourbusiness.co.ke:

• Create subdomains in DNS: shop.yourbusiness.co.ke for a store, portal. for a client system.
• Set up professional email (info@, sales@, yourname@) with your host or Google Workspace/Microsoft 365, using MX records (see the DNS and email lessons).

Summary

• A domain is your internet address; DNS points it to hosting, and you can change hosting without changing the domain.
• TLDs include .com and country codes like .ke; KENIC runs .ke and its second levels (.co.ke, .or.ke, .ac.ke, .sc.ke, .go.ke).
• Choose short, clear, brandable names; register through accredited registrars with accurate details in the true owner's name.
• Renew on time (auto-renew), understand grace/redemption periods, and use EPP codes for transfers.
• Protect domains with 2FA, registrar lock, working contact emails and good records.
