# Hostnames

Use hostnames when you want a specific hostname to resolve to a specified IPv4 address during Web or Desktop session execution, or when configuring a Web case. For example, use this when you want to connect to a different destination such as a verification server while keeping the same hostname.

{% hint style="info" %}
Configure a hostname and an IPv4 address. The hostname can be up to 253 characters and can include the wildcard `*`. You can add up to 50 hostnames.
{% endhint %}

3. In **IP address**, enter the IPv4 address to assign.

## Apply in sessions and cases

Apply registered hostname overrides when starting a Web or Desktop session, or as a Web case execution setting. The option appears only when at least one override is registered in memories.

To apply in a session, follow these steps.

1. On the new session screen, select **Web** or **Desktop** at the top of the screen.
2. Enter the scenario, start URL, and other settings.
3. In **Hostname overrides**, select one override to apply.

4. Click **Run Test**.

{% hint style="info" %}
**Hostname overrides** appears only for Web and Desktop sessions. It cannot be configured for mobile sessions.
{% endhint %}

To apply in a Web case, follow these steps.

1. From the case list, open the target Web case.
2. On the case detail screen, click **Edit**.
3. In **Hostname overrides**, select the checkboxes of the overrides to apply (multiple selection is allowed).

4. Click **Save Changes**.

{% hint style="info" %}
Web cases created with **Save as a case** from a session inherit the hostname override configured at session run time.
{% endhint %}

For how to create sessions and cases, see [Test session](/test-case-creation/create-test-session.md) and [Create cases](/test-case-creation/create-test-case.md).
