Velocity is an elegant DNS caching library for Python. It intercepts all the DNS/Protocol resolution calls and caches them.
That's it, everything that makes network connections gets a performance boost.

#### Installation
The recommended way to install **velocity** is by using pip as follows:
```
pip install velocity
```

#### Getting started
Velocity just needs to be imported to be activated.
For example, the following program will start using cached DNS responses after the first request.

```python
import requests
import velocity

for i in range(10):
     requests.get('https://s0md3v.github.io')

```

> **Important:** If you are using threads, consider caching the hostnames manually to prevent the database getting
affected from race conditions.

#### Managing local cache
The cache can be stored locally. None of the following methods return anything or take arguments, just call them at will.

```python
import velocity

velocity.flush_db()  # deletes the local cache
velocity.save_db()   # saves the in-memory cache locally
velocity.load_db()   # loads the local cache into memory
```

#### Manually caching hostnames
A hostname can be cached manually as follows:
```python
import velocity

velocity.cache(hostname)
```

> Note: IPv6 address are mapped to IPv4 addresses by default, which shouldn't be a problem. To avoid this behaviour and use IPv6 address instead, add an reachable port number as `velocity.cache(hostname, port)`

#### Accessing database
In-memory cache databases can be accessed with their respective variable names.
- `velocity.dns_cache` : Contains {hostname:ip} pairs
- `velocity.addr_cache` : Contains {hostname:getaddrinfo_object} pairs
