# How to use our proxies

> A step-by-step guide on using AltV6 proxies.

## Getting Started

Once you subscribe to a plan, you'll receive credentials to use our proxies. Your credentials will look like this:

```
http://abcd1234:abcd12456789@dc.altv6.com:3006
```

You can use them with any HTTP client. Here's an example using [curl](https://curl.se/):

```bash
curl \
    -x "http://abcd1234:abcd12456789@dc.altv6.com:3006" \
    "https://api.ipify.org"
```

## Proxy Configuration Options

AltV6 offers various settings to enhance your proxy usage.

### 1. Session Persistence

You can append a **session ID** to your username to maintain the same IP address across multiple requests. This helps avoid unnecessary IP changes.

**Example:**

```
http://abcd1234-session-abcdef:abcd12456789@dc.altv6.com:3006
```

* The session ID must be **alphanumeric only**.
* Length: **6 to 10 characters**.

### 2. Session Lifetime (TTL)

You can specify how long the IP address should remain assigned by appending a **TTL (Time-To-Live)** to the session ID.

**Example:**

```
http://abcd1234-session-abcdef-lifetime-10:abcd12456789@dc.altv6.com:3006
```

* The TTL must be a **number between 1 and 120**, representing the duration in minutes.

### 3. Location Selection

If you need an IP from a specific country, you can append a **location code** to your credentials.

**Example:**

```
http://abcd1234-country-us:abcd12456789@dc.altv6.com:3006
```

* The country code must be **valid**.
* Currently supported locations:
  * `us` → United States (More locations coming soon!)

## Frequently Asked Questions

### 1. Should I use HTTP or HTTPS?

Our proxy supports both **HTTP** and **HTTPS**:

* **HTTP:** `dc.altv6.com:3006`
* **HTTPS:** `dc.altv6.com:3007`

We recommend using **HTTP** because it works with all HTTPS-secured websites while avoiding additional encryption overhead, making it faster.

### 2. Is SOCKS5 supported?

No, AltV6 proxies only support the **HTTP(S) protocol**. SOCKS5 is not available.

### 3. Are IPv4 addresses available?

No, AltV6 proxies only support IPv6 addresses.
Websites without a `AAAA` record will not be accessible.

### 4. How much IPs do you have?

We assign each user to a dedicated subnet, our proxy pool is made of multiple subnets to avoid any IP block.
Subnets are varying in size, from `/80` to `/64` in size. Depending on the location and server, you'll have at the very least 280 billion unique IPv6 addresses available. In normal conditions, you'll have over a trillion unique IPv6 addresses available.

<Note>
  You can consult the size of the subnet with this tool: [/64 Subnet Size](https://www.vultr.com/resources/subnet-calculator-ipv6/?prefix_length=64\&display=long\&ipv6_address=%3A%3A%2F64), [80 Subnet Size](https://www.vultr.com/resources/subnet-calculator-ipv6/?prefix_length=80\&display=long\&ipv6_address=%3A%3A%2F80).
