We pick c.root-servers.net, one of the 13 root servers (1), and ask it about ask.fi and learn that fi is delegated to nine name servers (2), so we ask d.fi where we learn that ask.fi is delegated to two name servers, including ns1.zoner.fi (3), so we ask that one and get the following answer:
The two mail servers mailfw01 and mailfw02.zoner.fi together
Most of the several hundred of domains that use mail server group 1 use name server group 1 (example: rokkibeibi.com, pikkupaprika.com and css-galleria.biz ). Worth noting is that half of the domains that use name server group 1 use mail server group 1.
The two name servers ns1 and ns2.zoner.fi together
There are more than a thousands domains that use name server group 1.
Half of those use mail server group 1 (example: aitonet.com, autofoorumi.fi and emek.fi ). Worth noting is that three quarter of the domains that use mail server group 1 use name server group 1.
One quarter of them use mail server group 2 (example: niemela.com, hedelmapuu.com and laktoositon.com ). Worth noting is that most of the domains that use mail server group 2 use name server group 1.
The two mail servers mailscanner01 and mailscanner02.zoner.fi together
Most of the several hundred of domains that use mail server group 2 use name server group 1 (example: brionscientific.com, pyromanfx.com and stfu.fi ). Worth noting is that one quarter of the domains that use name server group 1 use mail server group 2.
