@kcclaffy Would you like to add the paper to the catalog -- usually we don't add papers that do not reference CAIDA datasets, but should we do it in this case?

We are going to add a new dataset WHOWAS with

• access link https://bttf-whois.as59645.net/.
• resource link https://arxiv.org/pdf/2211.06537v2.pdf
• review the paper and find the related datasets to link against

name: WHOWAS description:

WHOWAS is a ‘Backto-the-Future whois’ service, allowing historic bulk attribution of IP addresses on a daily granularity based on CAIDA Routeviews aggregates. 
We provide this service to the community for free, and also share our
implementation so researchers can run instances themselves.

We will add the paper https://arxiv.org/pdf/2211.06537v2.pdf as an external paper
