ISC's next webinar: DNS Wildcards

[Suzanne Goldlust]

A “wildcard” is a DNS resource record whose owner’s name starts with an asterisk. It sounds like a very simple hack to save time when creating a lot of similar names, but there may be cases where a wildcard is not what you want.

Please register at https://us02web.zoom.us/webinar/register/WN_7zTUZ6LxQVC-Iv6BWKToag to join us for an informative webinar on Thursday, November 10, 2022 at 19:00 UTC!

Our presenter, Carsten Strotmann, will explain:

	• What are wildcards good for?
	• How are wildcard names expanded?
	• Can wildcard domains have subdomains?
	• Can wildcard domains be empty non-terminal zones (ENTs)?
	• What about wildcards and NSEC/NSEC3?

He will also discuss some of the ways in which wildcards may interact with more modern features, such as CNAMEs, prefetch, serve-stale, and QNAME minimization.

We look forward to seeing you there! Thank you for your interest in ISC’s software.
