ISC DHCP is not affected. It doesn't act as a DNS resolver. This is a BIND server-side issue as the ISC KB describes: https://kb.isc.org/docs/cve-2026-3104 ISC DHCP uses portions of the ISC BIND libraries (primarily libdns, omapi, and libisccfg) only to support DDNS (TSIG support, DNS message construction/parsing, DHCID generation), OMAPI related operations, basic functions (configuration handling, data structures, logging, networking primitives).
