Domain Name Server (DNS)

Concept

1. Two type of DNS network activities:
   1. lookup: DNS client queries a DNS server for information
   2. zone transfers: DNS server (the secondary server) requests from another DNS server (the primary server)
2. DNS lookups are usualy executed usin UDP. (If some of data is lost in transit by UDP, the lookup will be redone using TCP)
3. DNS sever uses well-known port 53 (UDP/TCP)
4. Proxying characteristics of DNS:

BBEdit / BBEdit-Lite / TextWrangler Regular Expression Guide              Modified: 2018/08/10 01:19
————————————————————————————————————————————————————————————————————————————————————————————————————

NOTES: 

The PCRE engine (Perl Compatible Regular Expressions) is what BBEdit and TextWrangler use.

Items I'm unsure of are marked '# PCRE?'.  The list while fairly comprehensive is not complete.
