Bit mask cheat sheet
WebApr 19, 2024 · In C and other languages, you can use the above dynamic mask generation with constant values for n. That can make it easy to generate masks of interest. For example, a 4-bit mask (e.g. for the low nibble) can be generated using the constant (1 << 4)-1. A mask for the upper nibble of a byte is (the former) << 4. Other Operations

A 48-bit MAC can be transformed to an 64-bit interface ID by inverting the 7th (universal) bit and inserting a ff and fe byte after the 3rd byte. So the MAC 00:03:ba:24:a9:c6 becomes 0203:baff:fe24:a9c6. See RFC 4291 Appendix A and RFC 4941. IPv6 Address Scopes::/128 unspecified ...
WebApr 3, 2024 · Suppose we have a collection of elements which are numbered from 1 to N. If we want to represent a subset of this set then it can be encoded by a sequence of N bits (we usually call this sequence a “mask”). In our chosen subset the i-th element belongs to it if and only if the i-th bit of the mask is set i.e., it equals to 1.
