Recently I observed and noticed that, global IPv4 BGP table size has already grown over 1 million entries, around February to April time in this year, 2025.
I want to clarify this first. By the number “one million” I mean exactly the number “1,000,000”. I understand most people are more familiar with another number “1,024*1,024=1,048,576” as “1 Mega” something. We do not have that many BGP entries today yet. I believe just in weeks the global IPv4 BGP table size will also surpass this “1 Mega” number.
Will this event also trigger BGP packet forwarding problems just like that in 2014? I did a little research, and I found service providers’ routers in recent years have far more capacity than one million entries in hardware packet forwarding information base (FIB) entries. That is, no worry about any incidents at all. We can safely celebrate this “one million” day.
To all TCP/IP networkers, we are all Millionaires today.
One more thing…
How about the number of BGP entries for global IPv6? The global BGP table size for IPv6 is around 220,000, as of May 4, 2025.
