Hi, guys!

========== CASE 1

************ on keenetic
(config)> no ip host
Dns::Manager: Cleared all records.
(config)> ip host aaa.testmail.ru 192.168.1.100
Dns::Manager: Added static record for "aaa.testmail.ru", address 192.168.1.100.
 

*********** my laptop

$ nslookup aaa.mail.ru 192.168.1.1
Server:        192.168.1.1
Address:    192.168.1.1#53

Non-authoritative answer:
Name:    aaa.mail.ru
Address: 94.100.180.87

Address: 217.69.139.87

$  nslookup aaa.ail.ru 192.168.1.1
Server:        192.168.1.1
Address:    192.168.1.1#53

Non-authoritative answer:
aaa.ail.ru    canonical name = 2706909.sedoparking.com.
Name:    2706909.sedoparking.com
Address: 91.195.240.136

$  nslookup aaa.il.ru 192.168.1.1
Server:        192.168.1.1

$  nslookup aaa.l.ru 192.168.1.1
Server:        192.168.1.1
Address:    192.168.1.1#53

** server can't find aaa.l.ru: NXDOMAIN

+++++ It's ok, as expected.

Dns::Manager: Added static record for "testmail.ru", address 192.168.1.100.
(config)> ip host aaa.testmail.ru 192.168.1.100
Dns::Manager: Added static record for "aaa.testmail.ru", address 192.168.1.100.
(config)>

*********** my laptop

$ nslookup aaa.mail.ru 192.168.1.1
Server:        192.168.1.1
Address:    192.168.1.1#53

Non-authoritative answer:
Name:    aaa.mail.ru
Address: 192.168.1.100

$ nslookup aaa.ail.ru 192.168.1.1
Server:        192.168.1.1
Address:    192.168.1.1#53

Non-authoritative answer:

$ nslookup aaa.il.ru 192.168.1.1
Server:        192.168.1.1

Non-authoritative answer:
Name:    aaa.il.ru
Address: 192.168.1.100

$ nslookup aaa.l.ru 192.168.1.1
Server:        192.168.1.1
Address:    192.168.1.1#53

Non-authoritative answer:

+++++++++ now,
aaa.mail.ru
aaa.ail.ru
aaa.il.ru
aaa.l.ru 

points to 192.168.1.100? )))))))

WTF, why? I wasted my evening why I understood what is going on.
