RPKI is more effective than a competing /24. Unless they hijack you ASn

Dear team,
I have resorted to more specific announcements during hijacks, though
with only one purpose in mind: To buy us a bit of time while the
upstreams and peers put blocks in place to thwart the hijack as close to
the source as possible. The more specifics are an imperfect solution,
since t
I prefer the approach of disaggregating only when needed, not as a
preventative measure. There are tools that can help with automating this
disaggregation (ARTEMIS can do this, for example).

Folks can announce longer than 24 masks all day. They're unlikely to
propagate very far though, since most won't accept longer than 24 from the
world at large.
To the OP, there are some valid reasons to strategically deaggregate here
and there, but a blanket "yolo my entire allocation into /24s" s

Doubtful. Like I said, I did the math. The question I asked at the time was:
If:

I'm guessing you don't have any v4 to sell? If someone wants to give up
their space of their own free will that's wonderful, but I think most are
opting to sell their resources.

Rather than sell v4, why not return to the registry for free for
reallocation to those resource members with need.?

It should be 14M.
Worse, it will be reached unless we stop doing multihoming by
routing, which is selfish.

Yes, it is bad practice. Yes, it's polluting the route table.
If the # of /24s involved is not ridiculously large (say, <64?) them I would go
ahead, as long as IRR and/or RPKI are also updated.
Obviously if everyone did it (i.e. advertising /24s exclusively) then our FIBs
would collectively ball

Hi Billy,
I did some math on this years ago an
It's route table pollution if you ask me.. in today's world we have many
IXPs and several tier-1 operators that support RPKI ROV, so when you
have issued ROAs for the supernet of the IP space in question it'll
already significantly reduce the effects of a BGP hijack.

How does the community feel about using /24 originations in BGP as a
tactical advantage against potential bgp hijackers?
All of our allocations are larger and those prefixes we announce for
clients as well usually are. But we had a request recently to
originate everything as distinct /24 prefixes
Do you have any v4 addresses? If so, why don't you do 100% v6 and then
sell your v4 space for some extra cheddar?

It won't get them depeered, nor should it. I don't currently based much
value in RPKI for BGP.
