there is no difference
both the IP’s are of same Class C
Class C ip address has 24 networks bits and 8 host bits that’s why it is also represent with /24
ip address -
Subnet mask -

Class D - 224-239 is used for Multi-casting
Class E - 240 - 255 was reserved fro Research & development but currently they are simply wasted
