 | NetworkCidr Class |
Describes a IP network subnet using Classless Inter-Domain Routing (CIDR) notation.
Inheritance HierarchyNamespace: Neon.Net
Assembly: Neon.Common (in Neon.Common.dll) Version: 2.14.0
SyntaxThe NetworkCidr type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | NetworkCidr(IPAddress, Int32) |
Constructs a subnet from an IPv4 address and prefix length.
|
| NetworkCidr(IPAddress, IPAddress) |
Constructs a subnet from an IPv4 address and subnet mask.
|
Properties| Name | Description | |
|---|---|---|
 | Address |
Returns the CIDR address.
|
| AddressCount |
Returns the number of IP addresses within the subnet.
|
 | All |
Returns the 0.0.0.0/0 subnet which includes all public and private
IP addresses.
|
| FirstAddress |
Returns the first IP address in the subnet.
|
| FirstUsableAddress |
Returns the first usable IP address in the subnet.
|
| LastAddress |
Returns the last IP address in the subnet.
|
| Mask |
Returns the subnet mask.
|
| NextAddress |
Returns the first address after the subnet.
|
| PrefixLength |
Returns the prefix length in bits.
|
Methods| Name | Description | |
|---|---|---|
| Contains(IPAddress) |
Determines whether an IP address is within the subnet.
|
| Contains(NetworkCidr) |
Determines whether a subnet is completely contained within the current subnet.
|
| Equals | Determines whether the specified object is equal to the current object. (Overrides ObjectEquals(Object).) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Overrides ObjectGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Normalize |
Attempts to normalize a network CIDR string by ensuring that the
address actually fits the mask.
|
| Overlaps |
Determines whether this subnet overlaps another.
|
| Parse |
Parses a subnet from CIDR notation in the form of ip-address/prefix,
where prefix is the network prefix length in bits.
|
| ToString | Returns a string that represents the current object. (Overrides ObjectToString.) |
| TryParse |
Attempts to parse a subnet from CIDR notation in the form of ip-address/prefix,
where prefix is the network prefix length in bits.
|
Operators| Name | Description | |
|---|---|---|
 | Equality |
Compares two NetworkCidr instances for equality.
|
| (NetworkCidr to String) |
Implicitly casts a NetworkCidr into a string.
|
| Inequality |
Compares two NetworkCidr instances for inequality.
