• Feb 16, 2026 what wild card mask will match networks 1721600 through 1721900 1111 Looking at the binary, the common bits at the start are the first 20 bits: 10101100.0001 (172.16/12 to 172.19/12) This indicates a /20 prefix can be used to cover the range. The network address would be 172.16.0.0/20, which spans from 172.16.0.0 to 172.16.1 By Christine Okuneva
