Internet Routing Issue - IP ver4
I'm calling this a Routing Issue for lack of better or proper name to call this at the moment.
PC is connected via ethernet cable to 1gig IP ver4 router & internet access to Everything is fine, except for the following.
● All of my S3 buckets & files hosted on "objects-us-east-1.dream.io" are not accessable to the PC & receive HTTP access time out, & tracert to that server fails, (repeating time outs), after the 2nd hop. Typically The first 5- 6 hops in tracert's i do for any end point are Comcast servers (routers?) for my citty area.
● DreamHost support investigated & shows no issues on thier end.
● If i connect a laptop via WiFi to a nearby Hotspot, the laptop is able to fully access the "objects-us-east-1.dream.io" host & the S3 buckets & files w/o issue. Tracert to the host server also completes w/o issue
● However i noticed that the laptop connected via Wifi is using IP ver6.
Disabling IP ver6 on the laptop so that it uses IP ver4, results in the laptop loosing access to the host server & S3 buckets & files, and tracert to the host then also fails to complete, repeatly timing out after the 2nd hop. . . (same access & tracert issues as the PC)
● Soooo, what other trouble shooting info is needed,
And if not here on Forum, to who & how to report this ?
And what is a more technical name for this kind of issue ?
-----------------------------------------------------
● example of tracert to the host server that fails - under IP ver4.
Tracing route to objects-us-east-1.dream.io [208.113.201.33]
over a maximum of 30 hops:
1 12 ms 10 ms 9 ms 96.120.102.101
2 10 ms 12 ms 10 ms 24.153.84.69

Comcast does appear to be blocking that site's IP. My trace from Central PA looks like:
Notice that the trace never leaves Comcast's network. An IP is usually blocked for gross abuse, perhaps by another customer sharing that same DreamHost IP.
If an employee doesn't take care of this for you here, Comcast Security Assurance should be able to help. Give them a call at 1-888-565-4329 (from https://internetsecurity.xfinity.com/help/report-abuse). Note that this is NOT one of the general customer service numbers. The first-line reps there are sometimes not very helpful. If so, be persistent, and keep at them until you get a satisfactory answer.
You should also tell DreamHost that Comcast has blocked this IP. It is likely that the block won't be lifted until the behavior that triggered it has stopped.
I do not know why the site's IPv4 address would be blocked while its IPv6 address is not, but that situation has been reported previously for a different site: see https://forums.xfinity.com/t5/Your-Home-Network/Question-Can-You-Access-this-Website/m-p/3379827#M336511.

Likely a waste of time. Premise techs may not even know about IP blocks, and are not likely to be able to clear them. Blocks are set and cleared much higher up in Comcast's network management hierarchy.
But good luck!

update :
I called Customer Security Assurance this past Saturday. The agent "seemed to" understand what i was trying to report, put me on hold to several times, & each time when returning indicated he needed to transfer me to Comcast Internet Support. 4th time i said ok transfer me. At Internet Support i got escalated to higher levels & then maybe a tier3 agent, but the called then dropped rite away. (the agent on a cell phone seemed to be in low signal area)
Calling back i got escalated to either tier 2 or tier 3 (advanced internet support), & along with other testing & dialog they sent a home visit tech Sunday who verified modem signals are fine & internet connection works as expected.
Calling back yesterday was again was escalated to higher support levels, spent more than an hour on phone with the agent. Agent indicated she had also contacted a higher support level & was discussing with them. At this point they are sending a Tech out later today (monday), with the idea of having the tech do a more in depth testing of the modem related to IP4.
(imho : yeah i know, the issue is related to more than just one PC or modem & user IP address )
a case# is available for reference

Thanks re the good luck 🙂
The premise tech Sunday said as much.
paraphrasing - "we don't do that"
For now, I have time to be patient & let them arrive (via thier support protocals) at what we already know.

Will test the IPv4 & IPv6 when I get a chance as a temporary workaround, but doubt it will make much difference for my needs.
DreamHost also saying to use Cloudflare in conjunction with DreamObjects. Now to go through that process and see if it even helps with access, or if it is also blacklisted.
The hard block or blacklist prevents most clients from accessing files posted, which makes DreamHost useless moving forward unless this is entirely resolved by Comcast. I cannot filter internet access for clients or tailor specific delivery methods, especially when this is entirely a Comcast issue.
Works 100% fine via Verizon LTE cellular and via LTE hotspot to laptop. Issue is with Comcast entirely.
Issue isn’t even me personally accessing DreamObjects. Clients in this region are stuck with Comcast. Everyone working from home and no longer able to send clients files/links. Had been working last week.
