DNS Record

What is DNS Record?

RFC 1034 says the information about a domain name is composed of separate resource records, each with an owner name, a type, a class, a time to live and data. The types you meet most are A, which points a name to an IPv4 address, AAAA for IPv6, CNAME, which makes one name an alias of another, MX for mail, and TXT for free-form text used by SPF, DKIM and DMARC. See MX record and SPF record.

The time to live tells other computers how long to remember an answer before asking again.

Why does it matter on a fixed wireless connection?

A change to a record spreads as old answers expire, so a new website address may show for you before it shows for a neighbor. That delay is normal. It is also why a careful move keeps the old setup running for a day or two.

For a fixed wireless customer the records live with the domain's host or registrar, not on the roof equipment, and a change of internet provider does not change them. A home connection does not alter your domain. Read DNS records for your domain for the common cases.

What should I do about it?

Before editing, copy down the whole current list. Change one record at a time, keep a note of what it was, and test after each change. A missing dot, a stray space or a duplicate of a record that must be unique can break a site or mail.

If a domain is hosted by the company, call 775-575-9593 before you change anything. See nameserver for where the records live.
