[tech] DNS Name server change for gu.uwa.edu.au, was Re: [wheel] mooneye.ucc.gu.uwa.edu.au 130.95.13.9

[Nick Bannon]

Whoops - sent this, this morning, but:
- it's hardly confidential, so a copy should end up here; and
- we don't even know if it got through, yet: might need someone to
  forward it on from a student account; and
- drafts help, but still couldn't catch every typo!

Hi, Sandy! Looks like some emails went astray due to internal UWA spam
filtering, let's see if this one works. Thanks for the persistence.

Our tech-contact address is not strictly the one you used, it is:
wheel at ucc.gu.uwa.edu.au

- Our primary DNS server has changed to: monnik.ucc.gu.uwa.edu.au/130.95.13.2
- Our secondary DNS server has changed to: murasoi.ucc.gu.uwa.edu.au/130.95.13.1
  - possibly incorrectly firewalled
- Now that 130.95.13.9 is decommissioned and available, we are using it for testing

- ucc.gu.uwa.edu.au has been in continuous use as has ucc.asn.au
- unigames.gu.uwa.edu.au does not appear to be in active use
- unisfa.gu.uwa.edu.au does not appear to be in active use

- There was a parallel guild.uwa.edu.au domain - at one point that was a
  literal copy (symlink) of gu.uwa.edu.au on the Guild's DNS server machine,
  gumball/130.95.100.5 and its predecessors, and moved in steps to the
  Infoblox. It appears that the Infoblox (now) supports DNAME resource
  records instead, according to:

Thank you for the heads up, this part sounds fine to us.
