Oh go a head. I'm as anal as anyone.
Never say that on a technical list; you will surely find out that you are wrong.
but 209 210 and 211 are not class A but class C
Class A 1.0.0.0 - 126.0.0.0 Class B 128.0.0.0 - 191.255.0.0 Class C 192.0.1.0 - 223.255.255.0 Class D 224.0.0.0 - 239.255.255.255 Class E 240.0.0.0 - 255.255.255.254
Yes, this is correct. But you will find that blocks on these address blocks are implemented as if they were Class A's. i.e. block 209.0.0.0 - 209.255.255.255.
People still use the terms "Class A" and "Class C" a lot, but no one's done class-based routing in a decade or so:

Network blocks are often sold in */8 sized chunks, but "implemented as if they were Class A's" would imply that they were actually using an 8 bit netmask within the network. That just ain't happening ;)
