Jeewa notes that the kind of requests the Alfa Bank servers had been making had been what’s known as an “A report lookup.” (This is in response to the recordsdata which have been made public, which, he mentioned, might have been filtered to exclude different examples.) The area title system depends on area title servers (DNS), which act like a type of Internet cellphone ebook. If you lookup a enterprise in a cellphone ebook, you may see its foremost quantity, possibly a fax line, possibly some numbers for varied departments. DNS look-ups work the identical means: If a server desires to know contact trump-email.com, it contacts a DNS server to be taught its quantity — not a cellphone quantity, however an Internet protocol (IP) tackle, which is a string of numbers permitting Internet visitors to search out its vacation spot. Domains, just like the enterprise in our cellphone ebook instance, have completely different info obtainable about how they are often contacted. An MX report gives a pointer to the area’s email system (assume: fax quantity within the cellphone ebook). An A report is the principle cellphone quantity, the IP tackle internet hosting the area. It’s most likely essentially the most primary kind of area lookup request. That’s what Alfa Bank’s servers seem to have stored requesting time and again.
