        "description": "# hookdns\n\nHookDNS is a library which allow you to modify a name resolution in your Python script without any modification in your hosts file or by using a fake DNS.\n\n## Usage\n\nCustom DNS resolutions are describe by a dictionnary where the keys are hostnames\nand the values the expected corresponding addresses.    \n\n    {\n        \"hostname1\": \"addr1\",\n        \"hostname2\": \"addr2\"\n    }\n\nhostname and addr could be a domain name or a string representation of an IPv4/IPV6.\n\n### Example using the patch as a decorator\n\n```python\nimport requests\n\nfrom hookdns import hosts\n\n@hosts({\"example.org\": \"localhost\"})\ndef myfunc():\n    ...\n    r = requests.get(\"http://example.org\") # the request is sent to your local server\n    ...\n```\n\n### Example using the patch as a context manager\n\n```python\nimport requests\n\nfrom hookdns import hosts\n\nwith hosts({\"example.org\": \"localhost\"}):\n    ...\n    r = requests.get(\"http://example.org\") # the request is sent to your local server\n    ...\n```\n### Options\n\nBy default the following function calls are intercepted: *socket.gethostbyname, socket.gethostbyname_ex and socket.getaddrinfo*.\n\nYou can limit the interception to only a restricted list of function.\n\n```python\nimport socket\n\nfrom hookdns import hosts\n\nwith hosts({\"example.org\": \"localhost\"}, only=[\"gethostbyname\"]):\n    ...\n    addr = socket.gethostbyname(\"example.org\") # returns \"127.0.0.1\"\n    print(\"gethostname returns: %s\" % addr)\n\n    _, _, addr = socket.gethostbyname_ex(\"example.org\") # returns the real ip address for example.org\n    print(\"gethostname_ex returns: %s\" % addr[0])\n    ...    \n```\n```\ngethostname returns: 127.0.0.1\ngethostname_ex returns: 93.184.216.34\n```\n\n\n## Limitation\n\nIt works only with Python 3.4 and greater for the moment.\n\n\n",
