A helper class to make life easier while doing simple IPv4 address assignment in scripts.
uint32_t m_shift
shift, equivalent to the number of bits in the hostpart
uint32_t m_mask
network mask
uint32_t m_network
network address
uint32_t m_base
base address
Ipv4Address NewAddress()
Increment the IP address counter used to allocate IP addresses.
uint32_t m_max
maximum allowed address
Ipv4AddressHelper()
Construct a helper class to make life easier while doing simple IPv4 address assignment in scripts.
void SetBase(Ipv4Address network, Ipv4Mask mask, Ipv4Address base="0.0.0.1")
Set the base network number, network mask and base address.
uint32_t NumAddressBits(uint32_t maskbits) const
Returns the number of address bits (hostpart) for a given netmask.
Ipv4Address NewNetwork()
Increment the network number and reset the IP address counter to the base value provided in the SetBa...
Ipv4InterfaceContainer Assign(const NetDeviceContainer &c)
Assign IP addresses to the net devices specified in the container based on the current network prefix...
Ipv4 addresses are stored in host order in this class.
Definition: ipv4-address.h:42
holds a vector of std::pair of Ptr<Ipv4> and interface index.
a class to represent an Ipv4 address mask
Definition: ipv4-address.h:257
holds a vector of ns3::NetDevice pointers
Every class exported by the ns3 library is enclosed in the ns3 namespace.
