IPv4 subnet host count
H = 2^(32−p) − 2→Computer scienceIPv4 subnet address count
A = 2^(32−p)→Computer scienceNumber of IPv4 subnets
S = 2^(pnew−pold)→Computer scienceNetwork transfer time
t = 8V/R→Computer scienceProtocol efficiency
η = Payload / Frame × 100%→Computer scienceBandwidth-delay product
BDP = R × RTT→Computer sciencePacket serialization delay
t = 8L/R→Computer scienceRTT from distance
RTT = 2d/v→Computer scienceIPv4 prefix from host count
p = 32 − ⌈log₂(H + 2)⌉→Computer scienceSubnet addresses from host count
A = 2^⌈log₂(H + 2)⌉→Computer scienceDHCP pool size
P = H − R₁ − R₂→Computer scienceSubnet step from mask octet
S = 256 − M→Computer scienceIPv4 prefix and mask
/prefix ↔ netmask→Computer scienceIPv4 subnet summary
network = IP AND mask→Computer scienceIPv4 mask from host count
mask = prefix(H)→Computer scienceDHCP address range
usable range − reserves→Computer scienceIP in subnet
IP AND mask = network AND mask→Computer scienceIPv4 wildcard mask
wildcard = NOT mask→Computer scienceIP address and integer
