Curious question for people with their finger on the networking pulse: are there planned changes for BGP related to IPv6/IoT or will the current scheme scale well?

I'm assuming "many more" networked devices being added to the global network will eventually result in more traffic and more ASs being connected.

Short answer is "no".

Long answer is, actually these changes already happened quite a while ago.

Most of the time, we tend to forget IPv6 is in fact more or less 20 years old now.

Support for IPv6 in OSPF (OSPFv3) was introduced in 2008 and support for IPv6 in BGP was added in 2007 (MP-BGP).

AS numbers encoding was also changed in 2007 (32bits ASN) to support all those new connected system.
