Zdravim

Podle mne je to hlavne problem sysadmina na dane domene ze uziva
nestandardni odkazy v reverni tabulce. Tam by se podle mych zkusenosti by
se v reverzlookup nemelo objevit CNAME ale jen PTR. To ze se s tim novejsi
verze BINDu vyporadaji je dobre, ale starsi systemy s tim budou mit stale
problemy. Myslim si ze nameserver by mel byt udelany tak aby fungoval
korektne pro vsechny ( kdyz uz ne nameserver, tak co jineho ?).

Cast vypisu z reverzlookup:
>12.161.193.193.in-addr.arpa.    85336   IN      CNAME  
12.0-25.161.193.193.in-addr.arpa.
>12.0-25.161.193.193.in-addr.arpa.       85336   IN      PTR
