InetAddrUtils Types
enum	DtInetUtils::DtInetAddrFamily { DtInetUtils::DtInetAddrFamily_INVALID = 0, DtInetUtils::DtInetAddrFamily_IPv4 = 4, DtInetUtils::DtInetAddrFamily_IPv6 = 6, DtInetUtils::DtInetAddrFamily_Both = 99 }
Functions
bool	DtInetUtils::IN6_IS_ADDR_BROADCAST (const struct in6_addr *a)
InetAddrUtils Static Functions
Accepts a string representing an IPv4 address or IPv6 address, either standalone or as part of a network resource locator string. Returns the equivalent DtInetAddrFamily if the notation conforms to a valid form for the address type. Returns DtInetAddrFamily_INVALID otherwise. Note that if the string is a network resource locator string with a valid address part but an invalid modifier the whole string will be considered invalid.
DtInetAddrFamily	DtInetUtils::addrStringFamily (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) either standalone or as part of a network resource locator string.
bool	DtInetUtils::isIpv4AddrString (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) either standalone or as part of a network resource locator string.
bool	DtInetUtils::isIpv6AddrString (const DtString &addrString)
	Accepts a string representing an IPv6 address either standalone or as part of a network resource locator string.
bool	DtInetUtils::isLoopbackAddrString (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) or IPv6 address, either standalone or as part of a network resource locator string.
bool	DtInetUtils::isLocalhostAddrString (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) or IPv6 address, either standalone or as part of a network resource locator string.
bool	DtInetUtils::isLinkLocalAddrString (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) or IPv6 address, either standalone or as part of a network resource locator string.
bool	DtInetUtils::isMulticastAddrString (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) or IPv6 address, either standalone or as part of a network resource locator string.
bool	DtInetUtils::isBroadcastAddrString (const DtString &addrString)
	Accepts a string representing an IPv4 address (dotted decimal) or IPv6 address, either standalone or as part of a network resource locator string.
DtInetAddrFamily	DtInetUtils::parseNetResLoc (const DtString &nrl, DtString &parsedNrl, DtString &modifier, int &modifierType)
	Accept a string reference representing either a network resource locator and parses the string into the hostname, device name, or address with any optional modifier components and indicates what type of modifier was found.
bool	DtInetUtils::parseIpv4NetResLoc (const DtString &nrl, DtString &parsedNrl, DtString &modifier, int &modifierType)
	Accept a string representing either an IPv4 address in dotted decimal format or an IPv6 address in hexadecimal format with or without modifiers.
bool	DtInetUtils::parseIpv6NetResLoc (const DtString &nrl, DtString &parsedNrl, DtString &modifier, int &modifierType)
	Accepts a string representing an IPv4 address (dotted decimal) either standalone or as part of a network resource locator string.
DtU32	DtInetUtils::prefixLenToIpv4Netmask (DtU32 prefixLen)
	Convert a CIDR prefix length value to an IPv4 netmask in host byte order.
DtU32	DtInetUtils::netmaskToPrefixLen (DtU32 netmask)
	Convert an IPv4 netmask in host byte order to a CIDR prefix length value.
DtU32	DtInetUtils::convertStringToNetmask (DtString maskString)
	Accept a string reference representing either an IPv4 netmask in dotted decimal notation or a CIDR prefix length (eg.
DtU32	DtInetUtils::convertStringToPrefixLen (DtString maskString)
	Accept a string reference representing either an IPv4 or IPv6 netmask prefix length (eg.
DtInetAddr *	DtInetUtils::getPrimaryBroadcastAddress (bool preferIpv6=false)
	Attempts to find the primary device capable of broadcast and returns the broadcast address of the device.
const char *	DtInetUtils::removeZoneIndex (char *addrStr)
	Attempts to remove the zone index from the end of an IP string.
