How to read a suspicious link's real destination before opening it

Spot misleading website names in a link's host, username and path with reserved-domain examples, without visiting the destination.

The name before an at sign is separate from the actual host following it.
Illustration of the topic.

A familiar company name in a link does not tell you where the link goes. Check the URL’s hostname: the domain or IP address identified by a URL parser, excluding the port. Text before an @ can be a username, and text after a ? is part of the query rather than the hostname. MDN’s hostname reference and username reference describe those parts.

On a desktop browser, hover over the link to inspect the address the browser shows. You can also right-click, choose Copy link address, and paste it into a plain-text note. Do not paste it into the address bar and press Enter. Link text such as “View your example.org bill” can conceal a different address.

These parsed examples show why the whole hostname matters:

Address Hostname Detail to notice
https://account.example.org/billing account.example.org No username or port
https://example.org.billing-check.example.net/login example.org.billing-check.example.net example.org appears at the start, but the full hostname ends in example.net
https://example.org@account-check.example.net/login account-check.example.net example.org is the username before @
https://account.example.org:8443/billing?next=example.net account.example.org 8443 is the port; example.net is in the query
https://account.example.org.evil.example.net/login account.example.org.evil.example.net The familiar-looking prefix is only part of a longer hostname

Do not turn “check the last two labels” into a universal rule: country domains, public suffixes, and international domain names complicate that shortcut. A hostname tells you where the address initially points; it does not establish who owns a site or whether the site is safe. HTTPS alone is no guarantee against a scam, either. The FTC makes that point in its online shopping advice.

Practice with invented addresses

The address-parts exercise shows the hostname, username and other parts of a full HTTP or HTTPS address. Try the examples above, then choose Show address parts. Restore example brings back the address with an @. The page parses locally without opening the destination or following a redirect. It gives no safety verdict. Avoid entering private account-recovery or sign-in links.

When the destination is still unclear

A shortened link or redirect can hide the eventual destination. Inspecting the copied address cannot reveal where an untested redirect will end. If a message was unexpected, use a company phone number, email address, or website you already know is real instead of following its link, as the FTC advises for phishing messages. A search result is not automatically a safe substitute: the FTC warns that sponsored results can impersonate companies.

Source note: Sources were checked October 15, 2026. The five addresses above were tested with a headless Chrome 155 native URL parser using reserved example domains. None was opened; the test checked URL parts, not site reputation or redirect targets.
