## RECORDS

***
This is an easy one, what was the IP address in the first A record after we started using Cloudflare on our domain.
*** (domain is securebug.se)

first of all, try using DIG

```dig securebug.se```

securebug.se. 300 IN A 172.67.73.212

securebug.se. 300 IN A 104.26.0.66

securebug.se. 300 IN A 104.26.1.66

any of these ip's is correct answer. So I belive, that there was A record in the past and we should check DNS history.

portal ```securitytrails.com``` is good place to browse dns records history
