Servers, proxy, cache

  • pdnsd is a proxy DNS server with permanent caching (the cache contents are written to hard disk on exit) that is designed to cope with unreachable or down DNS servers (for example in dial-in networking). Since version 1.1.0, pdnsd supports negative caching.
  • nscd - name service cache daemon

Tools

whois domain.name
  • DNSYO is a little tool I built to help me keep track of DNS propagation. In short, it's nslookup, if nslookup queried over 1500 servers and collated their results.

Basic DNS Records

From DreamHost wiki;

A
Forward mapping of hostname to an IP address (66.33.201.141).
AAAA
Forward mapping of hostname to an IPv6 address.
PTR
Reverse mapping of an IP address (66.33.201.141) to a hostname (dreamhost.com).
MX
Mail eXchange records tell you which hostname to connect to for sending email.
CNAME
Say it, See Name, it points one domain name to another domain name, including mail service.
TXT
Text records, these are free form text strings, used for things like SPF.
SRV
Service records advertise a specific service a server offers. Zeroconf and XMPP Federation (Jabber and Google Apps) use SRV records in addition to PTR records.
NS
Delegates a domain or subdomain to another DNS server.
