resolveIPaddresses.php misses IPs and subnets?

[kuoirad]

I'm having a problem where scans appear to pick up what hosts are alive correctly, but DNS resolution is missing some random IPs and some whole subnets. Some subnets either aren't attempted to be resolved at all or resolution fails without any errors I can see. Other subnets have IPs show as alive but only some resolve to hostnames.

For instance, we use subnet 10.215.20.0/24. phpIPAM pings through the subnet just fine, but doesn't resolve any hostnames. In subnet 172.16.10.0/24, phpIPAM shows 172.16.10.107 and .108 as alive, but doesn't find the correct hostnames for them.

I am running phpIPAM 1.3.2 rev001 on Ubuntu 16.04. All subnets scanned are in RFC1918 address space, only available internally. The configured dns resolvers are our Active Directory controllers.

Please let me know what other information I can provide you.

• version of php?
• 32bit or 64bit php?
• Can you resolve names and ping Ok from the command line (ping/fping/dig/nslookup)?
