Dns server reverse lookup not updating
The default profile suggests that these files should be put in /var/lib/bind.
If you use an older version of Ubuntu, then you might want to check out the old guide, that was written for Ubuntu 8.04.This means that, as an address holder, you will have to configure two things.First, you have to configure your zone for reverse DNS.I liken it to the days when automobiles had carburetors; a mechanic could fix most engine performance problems by fiddling with the choke—spritz a little WD-40 into the throttle body, charge $50 and retire in the suburbs after a few years. Check the TCP/IP settings, run a few utilities to verify the zone records, charge $350 (correcting for inflation) and retire to Arizona.You’ll learn to identify the most common domain name system issues that cause problems for AD and Exchange and how to avoid them in the first place or isolate and resolve them if they occur in production.Second, you have to request reverse delegation of your zone.
The second part is done by creating a domain object in the RIPE Database.
If the TCP/IP settings for a member computer specify the IP address of a public DNS server—perhaps at an ISP or DNS vendor or the company’s public-facing name server—the TCP/IP resolver won’t find Service Locator (SRV) records that advertise domain controller services, LDAP, Kerberos and Global Catalog.
Without these records, a member computer can’t authenticate and get the information it needs to operate in the domain.
If you’re an experienced Windows system engineer, they may seem a little trivial.
But even the most highly trained and savvy administrator can get in a hurry and make a mistake.
The process of reverse resolving an IP address uses the pointer DNS record type (PTR record).
