    IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against ...

  3. Ingress filtering - Wikipedia

    en.wikipedia.org/wiki/Ingress_filtering

    In ingress filtering, packets coming into the network are filtered if the network sending it should not send packets from the originating IP address(es). If the end host is a stub network or host, the router needs to filter all IP packets that have, as the source IP, private addresses (RFC 1918), bogon addresses or addresses that do not have ...

  9. Ingress cancellation - Wikipedia

    en.wikipedia.org/wiki/Ingress_Cancellation

    Ingress cancellation is a method for removing narrowband noise from an electromagnetic signal using a digital filter. [1] This type of filter is used on hybrid fiber-coaxial broadband networks. [2] [3] If a carrier appears in the middle of the upstream data signal, ingress cancellation can remove the interfering carrier without causing packet loss.
