Command last displays wrong hostname

I faced an interesting problem on my AIX servers. When I checked last logins with command last I saw that hostnames are wrong. Let say, I made login from workstation xxxxx and with the command last I saw:

root pts/2 yyyyy 5 jan 15:38 still logged in

Ping xxxxx and ping yyyyy from AIX server are correct, nslookup is correct as well.
