IP topology does not equal geographical topology?

What is a topologically aggregatable address ? Or better asked, is the TAA a topologically aggregatable address?
E.164 telephone numbers are topologically aggregatable addresses. Indeed, in former days the mapping was done mechanically. Each digit selected the next link mechanically, even before the over-next digit was dialed. In West-Germany leading digit "3" was reserved for the eastern part for 45 years anticipating the reunion. So there is a real relationship between number and route/location.
 
I have my doubts wrt. TAA. Aren't TAAs just aggregatable addresses, ie. AAs?  I thought IP addresses  do not contain any topology information, no matter whether they are aggregatable or not.
