isInRange
Returns true if the parameteraddress
is in the range of usable endpoint addresses for this subnet. This excludes the network and broadcast addresses. UseSubnetUtils.setInclusiveHostCount(boolean)
to change this.- Parameters:
address
- A dot-delimited IPv4 address, e.g. "192.168.0.1"- Returns:
- True if in range, false otherwise
-
isInRange
public boolean isInRange(int address) Returns true if the parameteraddress
is in the range of usable endpoint addresses for this subnet. This excludes the network and broadcast addresses by default. UseSubnetUtils.setInclusiveHostCount(boolean)
to change this.- Parameters:
address
- the address to check- Returns:
- true if it is in range
- Since:
- 3.4 (made public)

getLowAddress
Return the low address as a dotted IP address. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.- Returns:
- the IP address in dotted format, may be "0.0.0.0" if there is no valid address
-
getHighAddress
Return the high address as a dotted IP address. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.- Returns:
- the IP address in dotted format, may be "0.0.0.0" if there is no valid address
-
getAddressCount
Deprecated.(3.4) usegetAddressCountLong()
insteadGet the count of available addresses. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.- Returns:
- the count of addresses, may be zero.
- Throws:
RuntimeException
- if the correct count is greater thanInteger.MAX_VALUE
-
getAddressCountLong
