-## What is this "renumbering" all about?
-
-As you may have heard, MIT has recently sold half of its IPv4 address space
-to Amazon in order to fund various network infrastructure upgrade projects.
-While there are enough remaining addresses for everyone and everything that
-was using one before, some rearrangement is required to make sure that
-everyone's IP addresses are in the smaller space that will be left after
-Amazon takes over the space that they have purchased. That takeover will
-happen later in June.
-
-All of the IP addresses used by VMs on XVM since its inception were,
-unfortunately, in the part of MIT's IP address space that has been sold to
-Amazon, and thus all of our IP addresses need to change. You can read the
-official explanation of this sale and MIT's upcoming network upgrades
-[here](https://ist.mit.edu/network/next-gen-mitnet-faq), but be sure to
-continue reading this FAQ, because IS&T's description of how the academic
-buildings and residence halls are being migrated does not apply to XVM.
+## What is this "renumbering" all about? Didn't we already do this last year?
+
+If you were an XVM user one year ago, you may remember having your VM(s)
+renumbered from IP addresses beginning with `18.181` to IP addresses
+beginning with `18.49` back then. We are being required to renumber
+again by IS&T. Please contact IS&T if you have questions about why
+we are being required to renumber. The process this time will be very
+similar, except that this time, addresses will be changing to ones beginning
+with `18.25`.
