Fast, fault-tolerant public IP address retrieval from Python or CLI.

The primary goal of this project is to find the public IP address (sometimes called an external
IP address) *reliably*. This means it works with or without UPnP, dual NAT, DNS manipulation by
the ISP, a VPN, or any single public web API or STUN server. It simultaneously queries multiple
external sources at random from a long list, recovers gracefully from failed queries, and does
not return an IP address unless all the responses agree.

### Installation

```
pip install myorigin
```

### Command line usage

```
$ myorigin -v

                                     requests in milliseconds (default: 12000)
  --minimum-match MINIMUM_MATCH      an IP address is considered valid after

  --majority-ratio MAJORITY_RATIO    minimum ratio needed to overrule a

                                     a value of 2 means 2:1, or that 6

                                     highly recommended if both IPv4 and IPv6
                                     are available, in order to avoid wasteful
                                     network traffic and unpredictable results

                                     will be received first, and sometimes
                                     IPv6 will win)
  -6, --ipv6                         use IPv6 only
  -l LOGFILE, --logfile LOGFILE      path for log file (default: write to

### Library import usage

```
>>> import myorigin
>>> args = myorigin.MyoriginArgs()
>>> args.minimum_match = 4
>>> myorigin.my_ip(args)
'88.123.8.180'
>>> 
>>> args.exception_level = 2
>>> args.ip_version = 6  # but there is no IPv6 on this LAN
>>> try:
...     myorigin.my_ip(args)
... except myorigin.NetworkError as e:
...     print(f"got error: {e}")
... 
got error: 10 requests failed; giving up
>>> 
```

### Features

* retrieves your IP address from any of 135 IP address providers
* confirms the correct IP address by checking muliple providers (default 2)
* recovers from failures by making additional requests of other providers
* keeps a record of past successes and prioritizes the fastest and most reliable providers from your location
* makes simultaneous IP address requests
* supports http, https, IPv4, IPv6

### Limitations

* has only been tested on Ubuntu Linux, though, being 100% Python, this *should* work on Windows, macOS, other Linux and BSDs, etc.
* has not been field-tested
