Best Practices

 <  Day Day Up  >  

The following are best practices from this chapter:

  • Use Windows 2000/2003 DNS or BIND 8.1.2 or higher to support SRV records.

  • Administrators should set up redundant name resolution servers in the event that one server fails.

  • Use caching-only DNS servers to help leverage load and minimize zone transfer traffic across WAN links.

  • Make any DNS implementations compliant with the standard DNS character set so that zone transfers are supported to and from non “Unicode-compliant DNS implementations , such as Unix BIND servers. This includes a “z, A “Z, 0 “9, and the hyphen (-) character.

  • Set up multiple MX records for all mail servers for redundancy. ISPs usually function as a secondary mail relay gateway for the hosted domain.

  • Always protect internal DNS servers and SMTP gateways by a firewall.
