Overview ¶

Only files including IPv4, IPv6, and Location (in english) will be read and parsed into lists.

Functions ¶

func IsEqualIPNodes ¶

func IsEqualIPNodes(expected, node IPNode) error

Returns nil if two nodes are equal Used by the search package

func PlusOne ¶

func PlusOne(a net.IP) net.IP

Types ¶

type GeoDataset ¶

type GeoDataset struct {
	IP4Nodes      []IPNode       // The IPNode list containing IP4Nodes
	IP6Nodes      []IPNode       // The IPNode list containing IP6Nodes
	LocationNodes []LocationNode // The location nodes corresponding to the IPNodes
}

The GeoDataset struct bundles all the data needed to search and find data into one common structure

func LoadGeoLite2 ¶

func LoadGeoLite2(zip *zip.Reader) (*GeoDataset, error)

type IPNode ¶

type IPNode struct {
	IPAddressLow  net.IP
	IPAddressHigh net.IP
	LocationIndex int // Index to slice of locations
	PostalCode    string
	Latitude      float64
	Longitude     float64
}

IPNode defines IPv4 and IPv6 databases

func LoadIPListGLite1 ¶

func LoadIPListGLite1(reader io.Reader, idMap map[int]int, glite1 []gLite1HelpNode) ([]IPNode, error)

LoadIPListGLite1 creates a List of IPNodes from a GeoLite1 reader Note that GeoLite1 is IPv4 only. TODO(gfr) Update to use recursion instead of stack.

func LoadIPListGLite2 ¶

func LoadIPListGLite2(reader io.Reader, idMap map[int]int) ([]IPNode, error)

LoadIPListGLite2 creates a List of IPNodes from a GeoLite2 reader. TODO(gfr) Update to use recursion instead of stack.

type LocationNode ¶

type LocationNode struct {
	GeonameID     int
	ContinentCode string
	CountryCode   string
	CountryName   string
	RegionCode    string
	RegionName    string
	MetroCode     int64
	CityName      string
}

locationNode defines Location databases

func LoadLocListGLite1 ¶

func LoadLocListGLite1(reader io.Reader) ([]LocationNode, []gLite1HelpNode, map[int]int, error)

Create Location list, map, and Glite1HelpNode for GLite1 databases GLiteHelpNode contains information to help populate fields in IPNode

func LoadLocListGLite2 ¶

func LoadLocListGLite2(reader io.Reader) ([]LocationNode, map[int]int, error)

Create Location list for GLite2 databases TODO This code is a bit fragile. Should probably parse the header and use that to guide the parsing of the rows.
