For me 2 have 2 domains, on second i have 20 hosts.
Whatever host i put first it will get reverse PTR record. No other host. I made workaround
Replace section of dbrev.mas. And added at end of original file all hosts manually. in format
% if ($groupip eq '20.20.10') {
1<----->PTR<--->router.egov.local.
2<----->PTR<--->soasuite.egov.local.
3<----->PTR<--->portal.egov.local.
4<----->PTR<--->portalnew.egov.local.
10<---->PTR<--->ldap.egov.local.
11<---->PTR<--->ssg.egov.local.
12<---->PTR<--->ssg.egov.local.
% }
