difference between forward and reverse lookup dns query

2) Batch file reads the input file and creates an output file such dnschecked.csv in which I can open in Excel and review the results on mass. This file will contain a list of server names. Memstatistics-file 'data/named_mem_stats. 1) Perform forward & reverse (FQDN, Shortname, IP) lookup on a server list that I will provide as an input file. The file should get stored at location ' /var/named/chroot/etc/nf' and symbolic link should get created at ' /etc/nf' which points to original file.

Note that link layer address in range fe80::/10 also get assigned to interfaces for auto-configuration, those addresses are not listed above.įirst we should configure logging, configure DNS server to listen on all IPv4 and IPv6 interfaces, define forward and reverse zones, etc. MAC addresses and IP addresses of vm1, vm2 and vm3 are: The whole setup is created on one single base machine using KVM and libvirtd. SQL queries on clustered and non-clustered Indexes. vm1 and vm2 are in one network and vm2 and vm3 are in other network so that vm2 can route both IPv4 and IPv6 packets between vm1 and vm3. Similarity between Forward index and Inverted Index: Both are used to search text in document or set of documents. Using following names and IPs to explain instead of the actual IP and Hostnames. At this stage (Network Settings) It checks only the DNS of VDP appliance. In our test network we have two networks connected by three machines vm1, vm2 and vm3. Verify both forward and reverse lookups are correct for both VCenter and VDP. Service Location (SRV Record)a service location record, like MX but for other communication protocols.

Certificate record (CERT Record)stores encryption certificatesPKIX, SPKI, PGP, and so on. We can configure IPv4 and IPv6, forward and reverse split DNS with bind so that same server can handle both IPv4 and IPv6 clients and at the same time give different responses based on whether query is coming from intranet IP, localhost or from global Internet, etc. Reverse-lookup Pointer records (PTR Record)allows a DNS resolver to provide an IP address and receive a hostname (reverse DNS lookup).
