minimumMTU

TypeScript

minimumMTU(useMinimumMTU: boolean): IP

Swift declaration

func minimumMTU(_ useMinimumMTU: Bool) -> IP

Configure IP to use the minimum MTU value. The minimum MTU value is 1280 bytes for IPv6 (`IPV6_USE_MIN_MTU`). This value has no effect for IPv4. - Parameter useMinimumMTU: True to use the minimum MTU value, false otherwise.

fragmentationDisabled

TypeScript

fragmentationDisabled(dontFragment: boolean): IP

Swift declaration

func fragmentationDisabled(_ dontFragment: Bool) -> IP

Configure IP to disable fragmentation on outgoing packets. Equivalent to `IP_DONTFRAG` for IPv4 and `IPV6_DONTFRAG` for IPv6. - Parameter dontFragment: True to disable fragmentation, false otherwise.

method · iOS 26.0+

receiveTimeCalculated

TypeScript

receiveTimeCalculated(calculateReceiveTime: boolean): IP

Swift declaration

func receiveTimeCalculated(_ calculateReceiveTime: Bool) -> IP

Configure IP to calculate receive time for inbound packets. - Parameter calculateReceiveTime: True to calculate receive time, false otherwise.

multicastLoopbackDisabled

TypeScript

multicastLoopbackDisabled(disableMulticastLoopback: boolean): IP

Swift declaration

func multicastLoopbackDisabled(_ disableMulticastLoopback: Bool) -> IP

Specify if multicast packets should be looped back for local delivery. By default, a multicast packet sent to a group to which the sending host itself belongs will be looped back for local delivery. `disableMulticastLoopback` disables this behavior and, if set, multicast packets will not be looped back to the sender. > Note: Only applies to multicast packets. - Parameter disableMulticastLoopback: True to disable multicast loopback, false otherwise.

method · iOS 26.0+

hopLimit

TypeScript

hopLimit(limit: number): IP

Swift declaration

func hopLimit(_ limit: UInt8) -> IP

Configure the IP hop limit. Equivalent to `IP_TTL` for IPv4 and `IPV6_HOPLIMIT` for IPv6. - Parameter limit: The hop limit.
