We’ve noticed that when the Hong Kong government sends emails they use the following servers / IP addresses.
For example:-
mail52.imail.scig.gov.hk [202.128.250.132]
In fact, from looking up on db-ip.com – it would seem that the the government owns this block of IP addresses.
202.128.250.0 – 202.128.250.255
The various government offices all seem to have different IP addresses provided by different suppliers
218.253.212.153 <= is the department of health’s IP address.
Interestingly, virtually all Hong Kong government sites are hosted in the US on this particular IP address 34.92.192.127
Sites such as:-
boardwalk.gov.hk
cleanharbour.gov.hk
dh.gov.hk
ehealthrecord.gov.hk
Around 200 websites are hosted on this US IP address which belongs to Google (it would seem if you do a web search); so Google is hosting many of Hong Kong Government’s website.
