dnsResConfigMaxCnames
Module: TIGER
OID (symbolic): TIGER::dnsResConfigMaxCnames
OID (numeric): 1.3.6.1.4.1.1978.2.1.10.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Limit on how many CNAMEs the resolver should allow before deciding that there's a CNAME loop. Zero means that resolver has no explicit CNAME limit.
What is dnsResConfigMaxCnames?
This read-write value limits how many CNAME redirections the resolver will follow before concluding there is a CNAME loop, per RFC-1035 section 7.1; a value of zero means no explicit limit is enforced. It defaults to 16. Admins lower it if they suspect misconfigured DNS zones are creating long or looping CNAME chains that waste resolution time.
