Like the decimal and hexadecimal addresses discussed in this thread, binary addresses are also acceptable for some TCP utilities.
The reply probably came from a router that could not forward the packet to the destination network. You can use traceroute to follow the process of a packet through the network to verify that.

hmmm, could this be right..?

Why would I get a reply from 209.44.32.146 when the example below states
that 11010001001111011011101011110001 = 209.61.186.121?
How do you find the binary for 3510483697? I know how to find the binary
from 209.61.186.121 - do you need a special tool to find the binary from
3510483697? or do you simply extend the 124-64-32-16 etc table up..?
And another thought, is it possible to filter on this level (3510483697)?
A very interesting thread!

Covert the large number to binary:
3510483697 --> 11010001001111011011101011110001
Break the binary up in 8 bit boundaries:
11010001 00111101 10111010 11110001
Convert each octet back into decimal:
11010001 --> 209
00111101 --> 61
10111010 --> 186
11110001 --> 121
Reassemble the individual octets into familar quad-dot addresses:
11010001001111011011101011110001 --> 209.61.186.121
