Technology and science fiction author Michael W. Lucas reports the adoption of Classless Interdomain Routing (CIDR) networking as a technology milestone in 1993. Back on 24 September 1993, the IETF published RFC 1519 thus designating Classless Interdomain Routing (CIDR) and variable length subnet masks as the standard which were further described in a series of RFCs. So Monday was the 25th anniversary of the occasion.
CIDR entry on Wikipedia notes:
Before the implementation of CIDR, IPv4 networks were represented by the starting address and the subnet mask, both written in dot-decimal notation. Thus, 192.168.100.0/24 was often written as 192.168.100.0/255.255.255.0.

Don't know/remember much about this classless routing.
But internet routing in general, separate protocols for internal routing and external routing to allow autonomous systems, modulating the routing table update schedule, discovering the route when only thing the dns gives you is IP address, all while reducing the routing table each router has to maintain to a manageable size, all these across all kinds of networks connected to the internet, managing all these, and pretty reliably, are indeed quite a remarkable achievement.
Some of you young'uns don't know shit because you don't have to because the shits have been worked out for you already. It's a shame that youth are wasted on the young.
