A domain extension, also called a top-level domain (TLD), is the part of a domain name that comes after the final dot, such as ".com" in dynadot.com.

Domain extensions can be generic or indicate a domain's purpose, industry, or geographic location, adding meaning and context to your web address.

Registration and renewal prices can differ because they are set separately and may reflect different wholesale costs, registry pricing, or promotional discounts.

In many cases, the first-year registration price is discounted, while the renewal price reflects the standard ongoing rate. You can stay informed by checking the Sales and Promotions page or subscribing to our newsletter.

It depends on the specific promotion. Some sales apply only to the first year of registration, while others may apply to multiple years, so you should check the terms of the individual offer.

Dynadot's pricing page (this page) and Sales page are the best places to confirm what sales we offer, while you can check renewal or multi-year registration prices on individual TLD pages. You can access each TLD page by using a TLD filter in the table on this page, where you can see all the info about each TLD. You can stay informed by subscribing to our newsletter.

Registering for multiple years can be beneficial because it may reduce administrative risk, help secure the domain longer, and protect you from short-term price changes.

The actual benefit depends on the extension, the registry's rules, and whether there is an active sale.

The best sales method depends on the domain and your goals. Common options include listing the domain in Dynadot's aftermarket, pointing it to a for-sale landing page, or using brokerage support if you want help finding and negotiating with buyers.

For investors, the right approach often depends on expected resale value, liquidity, time horizon, and the type of buyer you are targeting. If you're looking for a place to get some tips, read our domain investing guide.
