I did the netalyzr test which checks some ports and network configs.
The result was strange. It contained a problem with DNSSEC:
Only some DNS root server instances returned proper DNSSEC information. The working roots are: A, B, C, E, F, G, H, I, J, K, L, M
Do i need to worry because apparently the DNS Server from my ISP is unable to obtain information from all DNS root servers or can i ignore this warning?
