One says where the website is, another says where the mail goes, and others prove who may send for the name. A Wi-Fi router on a shelf. Stock photo: Adobe Stock. [Photo credits](https://hdiss.net/photo-credits/) ## 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](https://hdiss.net/glossary/mx-record/) and [SPF record](https://hdiss.net/glossary/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](https://hdiss.net/guides/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](https://hdiss.net/glossary/nameserver/) for where the records live. ### Sources - [rfc-editor.org/rfc/rfc1034](https://www.rfc-editor.org/rfc/rfc1034) (RFC 1034, IETF, November 1987; resource records, read 2026-10-15) - [rfc-editor.org/rfc/rfc7208](https://www.rfc-editor.org/rfc/rfc7208) (RFC 7208, SPF published as TXT, read 2026-10-15) ### Talk to a person - Call [775-575-9593](tel:7755759593) [775-391-5660](tel:7753915660) Open 9-5 every day - Email [info@hdiss.net](mailto:info@hdiss.net) [Check my address](https://hdiss.net/check-availability/#check) ### Related terms - [DNS](https://hdiss.net/glossary/dns/) - [Nameserver](https://hdiss.net/glossary/nameserver/) - [MX record](https://hdiss.net/glossary/mx-record/) - [SPF record](https://hdiss.net/glossary/spf-record/) - [DNS records for your domain: A, MX, CNAME and TXT explained](https://hdiss.net/guides/dns-records-for-your-domain/) Local since 2002 Fixed wireless from towers in Northern Nevada.
