Hello I am Taygun, I am a 23 year old who has been working in cyber security and information technologies as a hobby for about 13 years. There are countless people and institutions that have been victims of IP spoofing attacks that have increased recently in my country (Turkey). I started researching to find a solution to this problem and offer a solution to the ISPs and the IT institutions in my country. After brainstorming in the TRNOG group in Türkiye and on LinkedIn, such as NANOG, I thought that bcp38 could be a solution, but some people said that this solution would create a problem in multihome networks. What is the exact optimum solution? Where should I look? How can I create a plan that can be presented to the necessary places? Currently, all existing or old ISPs and datacenters in Türkiye have completely lost hope in resolving the problem.
