Final answer:
The binary IP address 11001110.00111010.10101010.01000011 converts to decimal as 206.58.170.67, each octet being translated to decimal format by applying binary to decimal conversion, making option (A) the correct answer.
Step-by-step explanation:
To convert the binary IP address 11001110.00111010.10101010.01000011 into decimal format, we need to convert each octet from binary to decimal. The process involves multiplying each bit by its corresponding power of 2 value and adding the results. The powers of 2 values for an 8-bit binary number (from left to right) are 128, 64, 32, 16, 8, 4, 2, and 1.
- First octet: 11001110 = (1×128) + (1×64) + (0×32) + (0×16) + (1×8) + (1×4) + (1×2) + (0×1) = 206
- Second octet: 00111010 = (0×128) + (0×64) + (1×32) + (1×16) + (1×8) + (0×4) + (1×2) + (0×1) = 58
- Third octet: 10101010 = (1×128) + (0×64) + (1×32) + (0×16) + (1×8) + (0×4) + (1×2) + (0×1) = 170
- Fourth octet: 01000011 = (0×128) + (1×64) + (0×32) + (0×16) + (0×8) + (0×4) + (1×2) + (1×1) = 67
Therefore, the decimal representation of the binary IP address is 206.58.170.67, which corresponds to choice (A).
